This suspension control arm and ball joint assembly is designed to match the fit, function, and performance of the original front lower rearward control arm on specified Tesla Model S and Model X vehicles. It has been thoroughly tested to help ensure a smooth ride, directional stability, and predictable driving dynamics, and is finished with a corrosion-resistant coating for long service life. The control arm comes complete with a pre-installed ball joint and bushings to save installation time and labor. To make this repair as predictable as it should be, we also include an aft link cam bolt, eliminating the hassle of sourcing that bolt. Using this bolt to replace the OE bolt that needs to be cut out can help speed removal and replacement of the arm.
