Installed a Denny's driveshaft and Dana spicer flange yoke on my 1964 Dodge Dart GT. The driveshaft replaced the old ball and trunnion style. I had rebuilt the old ball and trunnion style driveshaft but it was worn and vibrated. The new driveshaft runs great and has no vibration. It was also a perfect fit for my Dodge Dart. Thanks for doing a great job!! Steven

How ya guys doing. I ordered some driveshaft parts from the guys here at Denny's Driveshafts. I just wanted to compliment how fast the shipping was! Got to my house in 2 days. And they always sell quality parts. Don't hesitate to trust them with your order! Great company!

Jason D, Manhattan, IL, Mar 19th, 2015

I have received and installed my drive shafts and would like to take a minute to thank everyone at Denny's for the knowledge and patience in making sure I had what I needed and not just what I ordered. I am very happy with how the components fit as well as the quality. Your entire staff was always helpful and willing to explain to make sure I had what I needed and understood why I needed it. Thank you for everything.

Dustin S, Fort Wayne, IN, Feb 16th, 2015

We spoke Friday about mating a 350 to the 60 Willy's. Using your site with all the dimensions saved me from making a big mistake. I found I needed a GM 3R yoke and not a 1350. I felt real confident ordering from you with this info. Great help. Thanks again

GEORGE D, Feb 9th, 2015

I ordered a double cardan style driveshaft from Denny's for my CJ7. The team at Denny's worked with me along the way to make sure I had everything I needed for a seamless and trouble free installation.
The driveshaft went in without a hitch and the difference was night and day compared to my old driveshaft. I didn't think I had a bad vibration problem before but was shocked at how smooth the new driveshaft operated both while cruising and under acceleration.
The quality and value of the product is outstanding and the customer service was second to none. I would highly recommend Denny's to anyone needing to replace or upgrade their driveline.

Brian F, Jan 25th, 2015

I received the driveshaft just in time and it is impressive!
The quality is amazing. I will order another one for my 78 Trans am LS3 project from you for sure.

Thanks guys! Qaies Alkaldi, QATAR

My driveshaft arrived yesterday and I wanted to let you know how impressed I am with everything. The driveshaft is a perfect fit in every way and is beautifully made and finished. It was packed extremely well and arrived half way around the world (Australia) in top condition. Your customer service and quick response to emails has also been excellent. It's easy to see why your business has earned the great reputation it has. Thanks for an excellent driveshaft!

John L, Dec 22nd, 2014

I'm lucky owner of a 1967 Chevy Camaro SS RS Big block with a 427 engine. Car is a 1:1 Copo Camaro clone.
Since I own this California car now (4 years) I had to struggle with annoying vibrations in my drivetrain. This also wrecked my Muncie M-21 gearbox, 1 year ago and I had to replace it. I spent any effort to locate reason for this vibrations, during this I had the driveshaft balanced. Since I could not locate it and driveshaft was balanced I had no clue, where it will come from.
So, after lots of nights with thinking about it and some talks to my engine builder, we came to the result, to replace the driveshaft no matter what.
Then I start doing some research to find a good manufacturer for this new driveshaft. With my car I learned that even the best parts are good enough and will be hassle free.
Thanks to the lots of testimonials from happy customers all over the world I decided for Denny's!
This was the best decision, by the way.
I started reporting about my issue and sending some pics of my driveshaft. They could see on pics itself that this will match to my problem I told them about. This gave me some confidence that I might be on the right track.
I couldn't wait it until to have the new driveshaft at home. Even if he told an approximately delivery time of 4 weeks, the driveshaft arrived earlier. Shipping within 2 days from USA to Germany with UPS!
Unfortunately the driveshaft was 1.5 inches to short, my mistake. I get in touch with Denny and he was really willing to help me out and we had some nice email traffic. After I send him the right length of the driveshaft, measured multiple times to make sure not to make another fault, he really took any effort to build me a new driveshaft and had it shipped out within one week.
After I unpacked the new one (second) I first measured it and saw he build it exactly as I send him the new measurement.
I was pretty sure, this time I did everything right and it will fit.
Next day I bolted the driveshaft in my car and fits perfect.
Not to be to early with my enthusiasm I made a test drive.
WOW! I cannot say how much happy I am now. All the vibrations and noises from the body this vibrations caused in my car are gone!!
Its hard to believe its same car. Now it drives smooth and like a new car. No need to be afraid anything could break now when I push the pedal.
THANKS a lot for everything, Denny!!!

Stephan E, Sep 7th, 2014

Denny's built the driveshafts for my 68 Mustang ProStreet car and my 11 second 67 Chevelle Wagon bracket racecar. So when it came to finding a unique driveshaft for my 2001 Jeep Cherokee 4x4 Mud BogStreet cruiser, it was a total no-brainer who to turn to when I needed a shaft to connect my NP231 transfer case to my custom built Ford 9" rear axle. It arrived in a few weeks ready to bolt in and the fit was excellent. No vibration on my lifted Jeep whatsoever. When people ask me who built the driveshaft I tell um, Denny's are the go to people to connect any diff to any transmission, no matter how much power you put to the ground. I only wished they still put the contingency size decals in the box for the side of your racecar like they used to when they built my Mustang shaft back in 1997. Yep, I'm a lifetime customer!

Eddie B, Wailuku, HI, Jul 31st, 2014

I received my driveshaft and wanted to let you know that I am very happy with it. After bolting it in I lost that annoying harmonic vibe from the old shaft. Thank you for the fine workmanship and professionalism.

JOHN F, JACKSON, NJ, May 22nd, 2014

Got my parts sooner than expected , was exactly what I needed. You guy's are awsome!!!! You all will be hearing from me again soon. Having a Rear end noise. THANK YOU !!! Rene

Rene R, Casa Grande, AZ, May 21st, 2014

Hello Denny's Driveshaft,
I wanted to take a minute of your time to thank you for a Superb Product!!
Everything was just as you said from build time, to price, and ship date.
The Quality of workmanship and product material far exceed the standard. I
sincerely thank you for your 5 star services!!
Respectfully, Scott Edwards, CIV USAF AFDW-11WG (US)

SCOTT E, May 8th, 2014

I received my drive shaft the other day. It fit perfectly of course and looked so nice I hung it over the fireplace for a few days to admire it before putting it in the car.
Denny helped me with drive line angles and now the car is perfect!!!
Thanks to all

Mike Z, Ellington, CT, Apr 30th, 2014

Thank you for a great driveshaft for my roadster. It fit perfect and looks good too. The service was excellent and it arrived sooner than expected. It is nice to do business with a company that does what it says it will do.
Thanks again.

John N, lyndhurst, OH, Mar 16th, 2014

You guys are awesome... Extremely fast shipping... Quality Spicer parts, you had exactly what I was looking for at great prices, especially the CV bolts I needed that I couldn't find anywhere else for some really odd reason (you would think those are needed often...) I would definitely order from you guys again thank you!

Amy H, Shirley, NY, Mar 6th, 2014

What can I say? Not only did they have the correct part for my differential, the measuring was easy and when the product arrived, it fit perfectly, something hard to find in the world of hot rodding. Excellent advice and everything was spot on.
I will use Denny's again

Alan J, Green Bay, WI, Feb 22nd, 2014

Just wanted to give a shout out! I wish I would have got the mans name I spoke with on the phone. He deserves some praise. Once I explained my delima I was in and the urgency of getting the part overnight he went above and beyond to meet my needs. Im not used to customer service like this since everyone else "seems" not to care. Again thank you again for your superior service. Today is Thursday, I ordered yesterday and recieved the part this morning. You guys are the best and I will tell every one I know.

David P, Bristol, VA, Feb 6th, 2014

Professionalism at its best. A very knowledgeable and courteous staff. My questions were answered and, unlike other places I've dealt with, I wasn't expected to know more than the guy I talked with on the phone. An easy to navigate website, great prices, packaged very well,and fast reasonable shipping. I will be doing all my business through you. Thank you.

Wayne C, Jan 29th, 2014

I just put the new rear driveshaft you built for my 1977 F-150 4x4 short box and took it for a quick 10 km run --- truck drives like new and I am extremely pleased. Workmanship was excellent and I will be ordering a new front shaft in the near future.
Thanks for an excellent job and I will recommend you to anyone I know that needs a new driveshaft.

john h, Oldcastle, Dec 19th, 2013

Its very rare these days to find a company, either large or small, that will take extraordinary steps for customer satisfaction. However, Denny's Driveshafts is one such enterprise and the efforts they expend for their customers is unprecedented. If you have a need for either a complete driveshaft or individual components stop when you get to Denny's. You won't find better or more dedicated service!

Hi Daniel;
Its Marty Nelson... remember I bought a drive shaft from you for my 1948 Thames Panel..??
Well I just thought I would drop you a quick note to let you know that I finally healed
up enough ( cracked ribs) to install the shaft in my car! It fit like a glove... I have
been sweating and wondering if it would fit while I was unable to install it until now.
What a pleasure to be able to order a custom made item and have it actually fit! The
quality and workmanship is very evident in your product , especially for a car like mine!
It was a long process since I ordered it in Sept. But it was worth the outcome, and I
assure you everyone I know will be told about your drive shafts , and the A quality and
service I received at Dennys ! Its rare in this day and age to actually find a company
that truly cares about their customers and their satisfaction. Dennys seems to go the
extra mile to accomplish this. I must say that I greatly appreciate dealing with you
Daniel and all you have done to make me a satisfied customer!
Thanks a Million!
Marty Nelson

Marty N, Nov 9th, 2013

I've owned my 69 camaro for 9 years and it had a severe vibration when I got it. It went thru a 4 year restoration 4 years ago and I've replaced just about everything, and worked on pinion angles to no avail. I had my existing driveshaft shorten and rebalanced due to adding a overdrive trans, which didn't help, I even had a new driveshaft built locally which didn't help. Finally after talking to Denny I ordered a new HD steel shaft and my car is now smooth as silk! What a joy to drive now, thanks so much for a great product and taking the time on the phone to help me out!

Michael S, Schellsburg, PA, Oct 30th, 2013

I had Denny's make both front and rear 1350 series driveshafts for my 400HP Cummins diesel powered 4X4 (transplant) and am now fully confident that I won't be destroying them with too much push on the skinny pedal. The old shafts had tiny u-joints so I was always delicate on the clutch & throttle to avoid tearing them apart. The new shafts are as good looking as they are tough and functional, and the price was more than fair for the quality of the product. Denny's made the swap-over easy by including all my yokes and hardware in one well-padded package. The drive-line is now smoother and much quieter too. Thanks Denny and crew!!!

Eric M, CO, Oct 29th, 2013

After complete restoration of my 69 SS Chevelle I ended up with a vibration at 65mph. Was told it was a driveshaft issue and decided to upgrade to 700 lb. torque 5 speed which came with it own custom driveshaft. Still vibrated. Then had the 12 bolt completely rebuilt. Played with pinion angles. New wheels, tires, brake drums, you name it. Even installed another custom driveshaft from our local shop. Was about to give up. I was told about Denny's Driveshafts and had a new Aluminum Shaft made as a last resort. I have no vibration what so ever. 80mph and up. Thanks so much. Always was the shaft just had the wrong company make it.

Brian L, Hanover, PA, Oct 24th, 2013

Very much appreciate recent first-time order. The slip yoke replacement worked perfectly. In this day and age it is oftentimes difficult to find replacement parts which fulfill exactly as described. A Big Thank You!!! Will think DennysDriveshaft for all relevant future driveshaft needs!!!! Sincerely, Jeff Smith

Jeff S, Liberty Lake, WA, Oct 7th, 2013

I bought Denny's 3.5 inch Aluminum 6061-T6 Driveshaft with 1350 U-joints. My 65 Malibu had a vibration starting about 6000 RPM in high gear. I tried three different driveshafts... first from a friend then two that where built for my car (ALL VIBRATED). They all said "it wasn't the driveshaft it was my car". Well Denny's Driveshaft doesn't vibrate. Thanks Denny's

Willie M, Eatonton, GA, Oct 2nd, 2013

This site is the only place where I was able to find the parts for our 1996 Ford Frankentruck (that's an F-150 with all sorts of other parts from other Fords on it) at a reasonable price. Or at all for that matter. Having the dimensions listed on the website and the awesome amount of help when I called in was great. Thank you so much for all of your help!

Harmony P, Titusville, FL, Sep 13th, 2013

Just a note to thank you guys for the super job you did for me. The shaft is as smooth as any I have ever run. The car has picked up about 8 hundreds. You are very professional and patient while getting all the facts over the phone.
Thanks again,

Clyde W, Lexington , KY, Aug 26th, 2013

Just wanted to mention to you...I had been chasing a gremlin in my 67 Chevelle for years, a bad vibration since being restored. I tried everything. I knew it was not the driveshaft as I had this built for me by a "reputable" driveshaft shop in my area. Finally while pulling second hard at a high rpm, the M22 tail housing sheared off in the middle. I rebuilt what needed to be fixed and installed one of your shafts. Finally, the vibration was gone! It was the shaft!! You guys are great.
My Chevelle has never run smoother. Thank you!! I can now see out of the rear view mirror at 70 mph and actually see what is behind me.

Charles S, Jarrettsville , MD, Aug 26th, 2013

Just wanted to let you know that the new driveshaft fit and worked perfectly. The car was vibration free and the driver was happy. We finished 3rd in both our races at Watkins Glen this past weekend and are now qualified for the SCCA Run-Offs. Thanks for meeting our dead line too! Tim

Tim C, Chester Springs, PA, Jul 9th, 2013

I recently received the driveshaft that I ordered, and wanted to express my sincere thanks for job that you did. The driveshaft was delivered within the promised delivery date. More importantly, your driveshaft solved my severe vibration issue. I had a driveshaft constructed at a local shop and it demonstrated a severe high speed vibration that made the car undriveable. With your driveshaft, the vibration is gone, and I can actually drive the car now.
Thank you very much for a job well done!

Robert R, Lebanon , IN, May 20th, 2013

I received my 3.5" Nitrous Ready Driveshaft with the Chrome Moly Yoke today via UPS! It arrived packaged very well with zero damage. This driveshaft is for my 69' Pontiac GTO. I know it's been said before but I will say it again.... This driveshaft is a work of art! Great solid welds and great paint job as well! My Pontiac will be very happy and vibration free! Many thanks to Denny and the crew for excellent work. I will surely be passing your name on to others, I have always wanted a heavy duty 1350 series driveshaft and now I have the best!!!!!!!! Rock on!!!!!!!

Chris M, May 17th, 2013

Just wanted to take a minute to say THANK YOU for a great job!!! You came highly recommended and I can see why!!
The new driveshaft fit perfectly with absolutely NO issues.
I will pass your name on in a heartbeat. Thanks again!

JEFF C, WESTLAKE, OH, Mar 27th, 2013

I just received my driveshaft and the packaging was so good the shipping company couldn't even damage it.
The quality and the fit were excellent.
Very pleased!

jeff s, oakdale, CA, Feb 5th, 2013

Denny's Heavy Duty Steel Driveshaft arrived a week ahead of schedule and was packaged very well. Denny's truly pays attention to all the details because I found it to be meticulously crafted and painted. Denny's communication was great as well with prompt order confirmation and delivery tracking via Email. The shaft will be installed in my 1966, 327, 4-speed Nova Coupe. Denny's will get my future business!!!

Mark H, Dixon, IL, Jan 17th, 2013

Thanks for the quality drive shaft,fit like a glove.Great welds.

Steven S, Saranac Lake, NY, Jan 13th, 2013

I replaced my driveshaft with Part#: 1650788 for my 68 Mustang Coupe... all I can say is it's 100% total pro work! It's smooth as silk taking her up to 110 on the track. I went through several "factory" driveshafts, dumped money into balancing, etc... you can mess with cheaper stuff all the time, or just get it done right the first time and get one from Denny's.... it's one less thing I'll never have to worry about in my 68 coupe... pro work guys... you rock!!!

John B, Garland, TX, Dec 3rd, 2012

Easy order, fast shipping to Italy and high quality driveshaft for my jeep.

Gianguido L, Nov 20th, 2012

Received my Flange Yoke yesterday...It was half the price of the dealer and 2x the quality. Thanks Denny's for a great product and fast shipping to Canada.

wayne s, Sep 27th, 2012

UPS delivered my driveshaft a few days ago. Right away I was impressed with the extra care that was taken to package your product to prevent shipping damage. After opening box I am very pleased with the quality of the welds for an aluminum driveshaft. I was so close to using a local company to save a little money but after looking at a similar unit they produced and is now being returned for fear of breakage of the not to par welds. Thanks for producing a quality product.

Larry H, Alexis, NC, Aug 26th, 2012

I've been chasing a driveline vibration for so long. I tried pinion angles of all sorts and only made the vibration worse. I had the driveshaft balanced at a local shop only to find no difference. I read many driveline forums where other guys experienced similar vibes, and that is how I heard about Denny's Driveshaft. Other guys were extremely happy with the results so I thought "what do I have to lose, I tried everything else". Long story short I received my "Nitrous Ready" Driveshaft from Denny's the other day and the vibrations are completely gone! I highly recommend Denny's. I wont even think twice about where to get my next driveshaft from. Thanks to the crew at Denny's for putting the pleasure back into driving my car.

Jim K, from Canada, Aug 9th, 2012

Hi, Can't even begin to tell you how happy I am to have found your web site. You got me the Oldsmobile Drive shaft u bolts #38929 that I have been looking for for 8 months. Now this Project is moving, Both ways. In a positive direction. Thanks Again, Jim C.

James C, Madison, WI, Aug 1st, 2012

I would just like to thank your company for the quality
of the driveshaft I received today. It has the best looking
welds I have seen on a driveshaft. I'll know right where to
purchase my next shaft in the future. Thanks again.
Charles C

Charles C, Central Bridge, NY, Apr 4th, 2012

1969 Mach 1, 351W, T-5, 3:50 with Traction-Lok. Had a bad vibration starting at 65-mph. No fun. Finally decided that I had a bad driveshaft, both balance and length, were the source of my problem. Driveshaft length and length of slip yoke extending from the transmission tailshaft are so critical to a vibration free ride. Called Denny's and got exactly what I needed at a great price. Everyone was great to deal with. Installed the the new set-up, HD3-1310, and it fit perfectly. Went for a drive and vibration is completely gone. Finally!!!!

William L, TN, Mar 28th, 2012

Lightning fast processing and delivery. I received the parts within 24hrs (I live two states over). Will be back for more!

Paul E, Medina, OH, Mar 23rd, 2012

I am in the muscle car restoration business. About 6 years ago a local driveshaftaxle shop built me a shaft. On the way to a cruise night I drove the car 60 mph and the vibration was so severe the rearview mirror broke off the windshield. It felt like the fillings were coming out of my teeth!! Since then I gave Denny's a try. Thanks to the help from Denny, Mike and Daniel my fillings have held up and no more broken mirrors or windshields. Every car I build I use a Denny's Driveshaft. It has helped my business and my customers truely love to drive their cars. As far as I'm concerned there is no better driveshaft than Denny's! Your friend, Jim Q.

Jim Q, Harwich, MA, Mar 18th, 2012

Hello Dennys Driveshaft Team. Yesterday I received my parts.
I would like to say thank-you. The contact with you was super and the product is perfect. Juergen

Juergen S, Germany, Feb 3rd, 2012

Just wanted to let you know the new yoke, clamps and
seal arrived today and fit perfect. Just want to thank you
for the excellent service and I'll pass on your company

Robert T, Moose Jaw SK Canada, Dec 9th, 2011

Just want to say thanks, that was a fast delivery and
all the parts are a perfect fit.

Sam M, Girard , PA, Oct 11th, 2011

The half shafts arrived yesterday and look great. Thanks for you help and speedy service. Jeff

Jeff M, HOLLADAY, UT, Sep 24th, 2011

Received my driveshaft. Fits perfectly. You guys did an awesome job! Very happy with it. Thanks Lorne M

Lorne M, Sep 22nd, 2011

I just wanted to write a quick thank you to the EXCELLENT customer service I received yesterday. The gentleman on the phone not only knew driveline parts, he also wanted to be sure he could help with my pinion flange problems. I had purchased a U-joint from Denny's Driveshaft but only to realize my second Ford center section has a 1310 flange instead of the 1350 flange I had on my original center section. Everything I was told was absolutely correct. I had purchased this used rear and two center sections from a fellow racer. I had built everything correctly with the 6.33 center section (U joint, driveshaft length etc). What threw me off was the 5.67 center section. The 1 18 u joint caps will fit into the 1310 flange, after looking last night there is just the slightest gap. What the racer did before me was actually swap pinion flanges between the center sections to allow the driveshaft and u joints to work properly for the gear change. I made the switch last night and my entire driveline is happy. But I just wanted to write a thank you because the tech guy was excellent and I will be using your company for all of my future driveline parts. I will be racing Saturday night at Hagerstown Speedway (MD)- dirt circle track- in my Ford.

Brian S, MD, Aug 16th, 2011

I got it yesterday like you said. I put it on the car took it for ride about 3 pm and didn't stop driving until 10 pm.... No vibration.... it felt so good after 4 years and 5 driveshafts from local people who claim to know it all. They all told me it was not the driveshaft it was something else. I spent about 5 grand on these guys and now I'm rubbing it on their faces. I tell them they should give you a call and get educated. I'm planning on driving my car for a long time and thanks to you I'm going to enjoy it without vibrations. I'm very happy! Thanks Denny

Leslie O, Markesan, WI, Jul 25th, 2011

I love that this company had everything I needed in one stop. I shopped on line and would have had to buy three different items for my specific repair. Denny's not only had all three items, but they had it as a package deal! On sale! I wished I had found this web site a long time ago. THANKS!!!

LUKE M, Fort Drum, NY, Apr 9th, 2011

Just writing to say thanks. Nice looking driveshaft and fit just right. Don't rememeber his name but the fellow who took my order was really nice and easy to talk to. Good customer service.

kermit w, macclenny, FL, Mar 5th, 2011

Once again received a piece of art. Another well built driveshaft, even the paint was flawless. Only thing missing was the Denny's Stickers:(

Steven A, Hudson Falls, NY, Jan 25th, 2011

As always another perfect fit! Keep up the good work. Chuck's Classic Cars

chuck s, philadelphia, TN, Jan 19th, 2011

My problem wasn't as big as some peoples but none the less a problem. After 5 OTHER calls, I was done with it. Last call I got Denny who professionally made the driveline problem go away. Received parts on time fit perfect. Thanks! He took the time to TALK to me. Try and find that at other so called professionals. Again.. Thank You Very Much.

Harold P, apopka, FL, Jan 10th, 2011

Hi, I got my drive shaft and man, what a good looking piece of equipment. It fit first time, just like you said it would. My mechanic was impressed with the quality and fit. Everyone else who has seen it on the truck is quite impressed with it. I will recommend others to check out your work for their projects.

Alan J, Green bay, WI, Jan 1st, 2011

Want to thank these guy's for actually doing what most companies these days don't do "customer service" !! I ordered a slip yoke for my Ford E4OD and after receiving it found that it would not fit. The barrel diameter was bigger than what the E4OD will except. I placed a email to Denny's and the next morning got a call from Mike (sorry can't remember your last name). They had found that I was right in my measurements on the E4OD and sent me out a slip yoke that will fit... that day with no extra charge for the more expensive yoke and without even having the other sent back yet. Awesome!! Nowadays, you just expect to have problems with things like this, you know " well, you should've measured first and sorry but ..." There was none of that and I would recommend these guy's to anyone looking for drivetrain components! I will be a repeat customer for sure! Thanks, Adam Luanne

Luanne K, Edgewood, MD, Oct 25th, 2010

These guys are great ! I had been looking for a pinion yoke for my '94 Corvette as they are no longer produced by GM. Denny's showed them as backordered on their website and after calling, I found out that they were expecting a new shipment to come in by the next week.
I called a few times afterwards and the shipment had not arrived and they didn't know exactly when they would show up. I waited a few more weeks and called back and they had saved one for me, even though I hadn't left any specific contact information. This is outstanding customer service and I will use them and highly reccomend them for any future driveshaft needs.
Thanks again !

Ernest G, Cypress, TX, Jul 23rd, 2010

I just wanted to send a compliment. In 1992, I had an
old motorhome that I'd done an engine and tranny swap on and
needed a C-6 yoke for a 1350 u-joint. I found you in a
Street rod magazine. I've never once had an issue with your
yoke. I've taken that 6-ton vehicle up a 14% grade. I still
have that motorhome. Thanks for manufacturing a great

Byron S, Jun 24th, 2010

How often is it that you order a part from a company only to find out that after receiving the item you have to go ahead and fab up a cure for their mistakes. That is NOT the case with Denny's, the driveshaft I ordered was perfect, the fit, the balance, even the finish. After making a few passes with the car I have to say that they have a lifetime customer.
Thanks for the fantastic work.
Thomas Greene.

Thomas G, Durand, MI, May 31st, 2010

I've just receive my new street rod driveshaft.
It's marvelous!
Great communication with sales departement.
Very good!

Jerome L, May 27th, 2010

I have run a Dennys Driveshaft for two years now with nearly 500 quarter mile passes ,right out of the box it ran without any vibration and it is still that way today. That says alot behind a 1000 horsepower big block and 33-15 Goodyear slicks

Ron G, NY, May 1st, 2010

Hi Denny, Received your driveshaft today and it fits perfectly, thank you so much. It is always nice to deal with someone who builds a good product, is punctual, fair priced and above all, does what he says he will do, a quality which seems to have been lost by many in the hot rod business. Thanks again and I will be back. Ron Y

These guys are the BEST!! I broke my outer axle shaft on my dodge truck that I use to plow snow with two days before a big storm was going to be here. I searched here in Kansas City, MO and no one had the part. I found these guys online and ordered my axle shaft and did overnight air shipping. I called them the next morning to make sure I ordered the right part, the person I spoke to was very helpful and even thought of me needing a new axle nut, which I forgot all about. I told them my need to get the part ASAP and was told they would take care of it. My part was shipped before 6:00pm that night and made it to Liberty MO, at 9:46am the next morning. I was able to get my truck on the road before the storm and didnt miss any work. I will give these guys all my business and tell all my friends about them, I also race mud trucks so I am sure I will be talking to them before summer!!! Thank you so much guys!!

Denny it hase been a couple of years since I bought the aluminun shaft. The car has been on the road for a year now and it has 4000 miles on it. Had the car at 190mph while beating a Aston Martin vantage!! I'm not sure how much rpm your driveshaft turned but 5800 engine rpm 0.67 overdrive transmission and 3.42 rear end ratio. At that speed I had no unbalance problem what so ever. I'm currently working on a 7000rpm 700 hp Pontiac engine to get deep into the 200mph zone . Either with this car or the 69 GTO. Here is the address to a video clip at 170mph enjoy! ( scroll down it is in Dutch but you will see the video (surf for more highspeed footage) and also read the text above the clip.
