Denny's Driveshafts - One Good Reason is Enough!!!
If any one of these applies to you then it is time for a new driveshaft.
- REMEMBER we build driveshafts. We know what will work best in your application. Don't be fooled by a seller that doesn't actually build shafts. The internet is filled with online companies selling driveshafts that do not actually build anything.
- You have built more horsepower, torque and traction for this season and you are using your old driveshaft. It may now be questionable as to its ability to continue to handle the increased performance. It's an expensive gamble.
- Remember that your engine, transmission, ladder bars, frame, fuel pumps, tires and wheels are all items that can and will get damaged by a broken driveshaft when it happens. Can you repair or replace any of these for the price of one of our driveshafts?
- Don't kid yourself...if you think that adding nitrous or a blower doesn't mean that you'll need a stronger driveshaft. All that new horsepower and torque goes right through the driveshaft, doesn't it?
- Having a manual transmission always meant the necessity of a stronger driveline. With the increase in cars with automatics and tranny brakes, this now means the car is going to need a stronger drive shaft to handle the "neck snapping" launch.
- An old saying "out of sight....out of mind" often applies to the driveshaft. You really need to consider what you may be doing, whether on the street or the track, and decide if you are willing to compromise strength at any cost.
- A very common call that we get, is one where the customer wants to know if we can balance their oem driveshaft to run at a high RPM like ours will. This is just not physically possible in most cases. The OEM driveshaft, or one built like it, was not built to handle this high RPM smoothly. It was built to run at best 4000 RPM. Now you are buzzing that same shaft at 7000 RPM or greater and the whole car will "buzz" with it. We cannot make your driveshaft go as fast as one of our CUSTOM MADE HIGH SPEED BALANCED DRIVESHAFT ASSEMBLIES and an oem driveshaft definitely wasn't built to do it.
- Vibration is a big concern when it comes down to a quicker ET, not to mention the annoying effects of driving any vehicle that has a driveline vibration. We can build you a driveshaft that will go the RPM that you need and do it smoothly. Now you can enjoy your ride and a quicker ET.
- At DENNY'S one call can bring it all. The only thing that you need to do is measure it correctly as our worksheets show and it will fit every time. It is very easy to have the driveshaft that you need in your car, so don't let your "lack of experience" stop you. Believe me "a lack of experience" in regards to failure is a good thing. If you have had the "experience" then you know you need STRENGTH and RELIABILITY.
- We have the parts and the experience to provide you with the finest driveline components that you can buy. We can connect just about any transmission to just about any rear end and we do it best, BECAUSE THIS IS ALL THAT WE DO.

DISCLAIMER OF WARRANTY: No warranty express or implied applies to any part or service offered by DENNY'S DRIVESHAFT SERVICE INC. Purchaser or user assumes all risks from the use of any item or service purchased or acquired. Purchaser is advised to have a properly constructed driveshaft loop or loops installed prior to installing and using the driveshaft. We will however, replace the driveshaft or refund the full purchase price as described on the original invoice to the original owner if weld breakage or tube twisting or tube breakage occurs. Not to exceed the original advertised statement involving the description "If you ever twist our steel tubing or break our steel welds...we'll replace it FREE". If a u-joint breaks and damages the entire unit the replacement of the drive shaft will be at the expense of the owner. We cannot be responsible for universal joint breakage due to the many circumstances that we have no control over. Excessive joint angle, lack of maintenance or improper universal joint series due to the purchaser understating the intended usage, or the addition of horsepower over and above that which the driveshaft was originally built for, improper installation, usage of driveshaft in another vehicle other than the one it was built for, to name a few examples. We cannot be responsible for conditions that we have no control over. Driveshafts purchased from a vendors catalog, driveshafts purchased from a car builder or any source other than directly from Denny’s must be handled through the original seller. Please contact them directly. If you purchase a used driveshaft from an online auction, such as ebay, or from a classified ad or swap meet be very careful to be sure the driveshaft is really a Denny’s Driveshaft. If you know the original purchasers name you can verify its authenticity by calling us. The fact that the driveshaft has a sticker or label on it with our name on it does not mean it is one of our driveshafts. There has been a few cases in which our decals have found their way onto a driveshaft that we did not build.
