1999-2002 Audi S4 2.7T 6-Speed Manual 1000HP Direct Bolt-In Axles.
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.
Fits: B5 Audi S4 2.7T with Manual 6-spd
