The C2 Hub splines are generally the first weak link when adding power to the Allison 1000. A sudden jolt in traction can be just enough to strip the splines out of the hub, then ruining a much more expensive part. The P2 Planetary. We have made a budget friendly part to help strengthen the spines in the hub. When the splines strip they expand the snout of the hub out. We have machined a press fit sleeve to help hold the snouts shape when under load. This a must for any units built to hold UP TO 700WHP. Great for DIYers, and seasoned builders.

The P1 sun gear MUST be machined to fit the sleeve.

The factory 68RFE valvebody has many downfalls. Most of the time leads to needing a complete unit rebuild due to overdrive clutch burn up. The factory valvebody will only allow the transmission to make 160 PSI of line pressure. Our valvebody has been modified to make 225 PSI. This added pressure is a must for longevity/holding power. Stock or modified its a good idea to upgrade from the problematic factory valvebody.

Nothing like billet bottom parts. It’s a shame to cover it all up.
