Denny's Driveshafts stocks the Chevy 12 Bolt rear end pinion yokes in a variety of u-joint series in the 30 spline version.
The Chevy 12 Bolt rear ends can be found in just about any Chevy and GM car or light truck. Chevrolet enthusiasts around the world have used the Chevy 12 Bolt rear end in countless street and race car applications.
The original equipment u-joint size was either 1310 or 1330 series. The 1310 series is commonly known as the "small" u-joint and the 1330 series is known as the "large" u-joint. Both of these can be found on the Chevy 12 Bolt rears. There is also a third original equipment version, the General Motors 3R series, that could also be found on the 12 bolts.
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 1330 series in the original equipment u-bolt style or strap and bolt style and we also have the 1350 series Forged and Chrome Moly pinion yokein the u-bolt style, a much stronger way to go.
