Driveshaft Shop - Rear Axle Bar / Internal *Upgrade Only* || F10-F13 M5/M6

The Rear Axle Bar and Inner CV upgrade for the F10 M5 is now available. We have developed a set of axle bars, inner CV, and outer CV internal upgrades. Using our 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. Our Chromoly 108mm inner CV is a direct replacement for the stock unit and features full aerospace grade internals. The factory M3 outer CV housing is made from a very strong material, and we upgrade the internals to an aerospace grade set also.

You must send in your factory OEM axles so we can assemble this set. We will temper and shot-peen the outer housings, install factory-style metal covers on the outer CV (double o-ring sealed), and install our new cage/race internals along with 36 spline bars and 108mm inner CV. Rated to 1200HP with a 1-year warranty.

**You must send in your axles to have this process done, please call for lead times and an RMA number before sending them in.**

Warranty: 1-year
