Driveshaft Shop Audi S4 B5 Chassis 1998.5-2002 1000hp Front Axle bar and inner C.V. upgrade
The S4 Front Axle Bar Upgrade. The factory inner and outer CV are made from a very strong material, but the axle bars are very brittle with machined steps that create concentrated stress points that are prone to failure especially with higher horsepower.
This axle upgrade includes a pair of our aerospace grade torsional axle bars and inner CV's, and upgraded CV internals to upgrade the factory outer CV's to use the larger spline bars.
