Product Details

If you have added a large amount of horsepower to your vehicle, chances are the stock drivetrain is not ready for the abuse. Furthermore, the factory axle shafts in the back were not made to withstand anything over the output of the original car and quickly become the weakest link in the chain.

Enter these upgraded rear cv axles from The Driveshaft Shop. These are your own axles that we will send out and have Driveshaft Shop work their magic. The outer housings will be shot-peened and tempered and metal covers will be installed on the outer cv with a double o-ring seal. Inside new cage/race internals are installed capable of handling extreme amounts of power with a 108mm inner cv. Finally, the bars are changed out for aircraft grade with 36 splines instead of the factory 28. When they are finished these cv axles boast a strength of up to 1000hp and come with a one year warranty.

In order to have this process done, your old axles must be removed and shipped. Please call for further details.
