BMW 428i Ball Joint Kit - Front - Dinan Monoball Kit (2014–2020). Replace the factory rubber thrust arm bushings with precision monoball joints for sharper steering response and more consistent braking control.

Dinan’s cartridges press into the front lower control/thrust arms, using machined aluminum housings and nylon-lined bearings sealed with rubber boots. By eliminating bushing deflection, they tighten on-center feel, sharpen turn-in, and help reduce brake shimmy—yet remain quiet for daily use. Fits BMW 4 Series F32/F33/F36 (2014–2020), including 428i/430i/435i/440i; not compatible with xDrive.
