German Auto Solutions is proud to offer you our GAS Performance solid ball joint monoball suspension upgrade kit for the F20-F30 xDrive Series BMWs, pre-installed into new control arms.

This product is only for the xDrive version of the F20-F30 Series BMWs. Find the RWD version here.

Our Monoball upgrade replaces the stock rubber bushings in the front control arms with sealed, solid ball joints. This upgrade will result a significant handling improvement via more precise steering control and improved steering feedback. Monoballs also ensure that toe and camber settings are retained under high cornering loads which would otherwise cause the stock rubber bushings to deflect.

This performance suspension upgrade consists of new BMW German made sealed solid ball joints, CNC machined anodized aluminum ball joint carrier housings, stainless steel mounting collars, and stainless fasteners, all pre-installed into brand new control arms. Like all G.A.S. products, our monoball kit components are CNC machined by us here in the U.S.A. to exacting tolerances. We believe that you will not find a higher quality monoball kit anywhere else at any price!
