Here is a product that has been demanded for many years. When we started racing our S2000 and suffered the failures many have, we started looking for a solution. With this taking almost a full year to complete the setup, it is finally ready for abuse! Horse power rating is very subjective and will depend on what you do with the other parts in the diff, the caps will no longer be the issue in breaking or flexing causing failure!
What is all included 4140 Billet caps, Breather cover, and ARP bolts.
*Tolerances should be checked for bore roundness as each diff housing has its variances along with using ARP hardware and torques specs can also cause out of round conditions.
