Driveshaft Shop Rear Axle Bar and Internal CV Upgrade, BMW F8X M3 / M4

DSS Rear Axle Bar and Inner CV upgrade for the 2014+ F80 M3, F82 and F83 M4

DSS has developed a set of axle bars, inner CV, and outer CV internal upgrades. Using their 36 spline high-grade aircraft quality bars (stock axle bars are 28 splines), custom Chromoly CV cage, and race set makes these axles practically indestructible.

DSS's Chromoly 108 mm inner CV is a direct replacement for the stock unit and features full aerospace grade internals. The factory M3 / M4 outer CV housing is made from a very strong material, and we upgrade the internals to an aerospace grade set also.

Customer must send in OEM axles for assembly.

DSS will temper and shot-peen the outer housings, install factory-style metal covers on the outer CV (double o-ring sealed), and install their new cage/race internals along with 36 spline bars and 108mm inner CV.

Rated to 1200HP with a 1-year warranty.
