Driveshaft Shop Rear Axle Bar and Internal CV Upgrade, BMW F1X M5 / M6

Upgrade your BMW F10 M5 or F13 M6 with Driveshaft Shop’s 1200HP-rated rear axle bar and CV upgrade, engineered for extreme performance. This service strengthens your factory axles with high-grade 36-spline aircraft-quality bars, a custom Chromoly CV cage, and an aerospace-grade race set, making them significantly more durable than stock components.

The service includes tempering, shot-peening, and installing factory-style metal covers on the outer CV for enhanced durability and sealing.

This is a send-in service. Customers must send in their OEM axles for the upgrade process.
