Chevy and GM 8.5 inch 10 Bolt Front and Rear End Pinion Yokes ...30 Spline

Denny's Driveshafts stocks the Chevy and GM Corporate 8.5 inch 10 Bolt front and rear end pinion yokes in a variety of u-joint series in the 30 spline version. 

  • The 8.5 inch 10 Bolt FRONT has a 30 spline pinion gear and is typically found in 1978 to 1987 Chevy and GMC K5, K10, K15, K20, K25, K30 4x4 trucks
  • The 8.5 inch 10 Bolt REAR has a 30 spline pinion gear and was first used in 1970 and has evolved into the 8.6 inch in 1999.  The 8.5 can be found in just about any Chevy and GM car or light truck.  Chevrolet, Oldsmobile, Buick and Pontiac enthusiasts around the world have used the 8.5 inch 10 Bolt  rear end in countless street and race car applications.  

The original equipment u-joint size was either 1310 or GM 3R series.  The 1310 series is commonly known as the "small" u-joint and the 3R series is known as the "large" u-joint.  Both of these can be found on the Chevy and GM Corporate 8.5 inch 10 Bolt rears. 

The original equipment hardware used to hold the u-joint into the pinion yoke was comprised of either two 5/16 inch u-bolts or 4 bolts and 2 metal straps.  Both styles were used on original equipment applications. 

We can supply both the 1310 series and 3R series in the original equipment u-bolt style or strap and bolt style and we also have the 3R Chromoly u-bolt syle and the 1350 series Forged and Chromoly pinion yoke in the u-bolt style, a much stronger way to go.  There is also a Spicer cast 1350 series strap and bolt style available for those on a budget.

The ultimate in strength and reliability is the 1350 series.  The Chevy and GM 8.5 inch 10 Bolt  30 spline pinion can now benefit from the simple installation of a 1350 series pinion yoke.
