The Rear Axle Bar and Inner/Outer CV Housing Internal upgrade for the BMW F10-F13 M5/M6 is now available. We have developed a set of 300M axle bars, Chromoly Inner and outer CV internal Components. Using our Proprietary 1.25″ Diameter high-grade 300M quality bars (stock axle bars are 28 splines), custom Chromoly CV cage, and race set makes these axles practically indestructible. The factory M5/M6 outer CV housing is made from a very strong material so this Upgrade will be more than enough to handle the 1200hp Rating offered.

You must send in your factory OEM axles so we can assemble this set. We will temper and shot-peen the OEM Outer/Inner housings, install factory style metal Boot covers on the outer CV (double o-ring sealed), and install our new Chromoly cage/race internals along with 30 spline bars. 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.**
