Product Details

This Whiteline Rear Lower Rearward Control Arm Kit fits the 2015-2023 Ford Mustang (S550). Application note: Replaces large forwardmost inner compliance bushing on both rear lower control arms. In the box: 2 shell bushings and 2 tubes. Chassis code: S550. Order it as part number W63498. Position: rear.

The arms are what keep a wheel tracking correctly over bumps, under braking, and through corners. When their bushings wear or the arm bends, alignment changes under load. A replacement set puts a sound arm back on each side. The polyurethane used here deflects much less than the original rubber under the same load.

Installation is rated moderate, with about 2 hours of work listed. Get the car aligned once it is back on the ground. Working on the same car? We also list Adjustable Rear Sway Bar Link, Adjustable Front Sway Bar Link, and Front and Rear Sway Bar Kit for the Mustang.
