This is a set of axle bars and internal Chromoly parts to upgrade the rear axles for the 99-05 Audi S4. The factory axles are made with a major flaw, being that the outer spline is a small 30 splines and inner is a bigger 33 splines, making the end of the bar at the outer CV receive excessive concentrated stress. What we have done is make high grade internals for both the inner and outer CV's to be able to put one of our larger 36 spline torsional center bars on the factory CV's. Initially the front axles were normally the main issue with this car, but as the bar has been raised on this platform, so has the need for stronger axles.
