Pontiac GTO: Rear Differential

OE CV axles typically won´t fail because the driveshaft goes first. Once the driveshaft is upgraded, the CV´s become the next weak link and typically break at the axles´ transition on the shaft. A broken CV axle can cause thousands of dollars in damage before getting the car stopped. Don´t risk it, our heavy duty CV axles use custom billet CV joints and 300M axle material. The axle itself is 1-3/8" diameter compared to the OE 1-1/16" and is capable of handling 800+ RWHP

 The factory stub axles are fairly strong however they become the next weak link once the half shafts and driveshaft have been upgraded. Our heavy duty stub axles are made from 300M billet, the strongest axle material made, and come with an OE zinc finish to prevent rust.

These custom differential covers stabilize the differential mount, reinforce the case, and provide better cooling with increased oil capacity. The factory rear mount is a very poor design. The entire rear cradle and suspension is mounted by two front bushings and one rear. The rear center mount attaches to the cover and is responsible for controlling movement and maintaining pinion angle. This improved rear mount spreads the load out over a greater area by using two bushings, each to the side of the cover. Less differential flex results in minimized wheelhop and quicker response to braking and acceleration. Simple bolt-on installation. NOTE: Although this cover clears OE exhaust, aftermarket exhaust systems may require modification.   ´04-´05 Pontiac GTO
