Eliminate Deflection. Kill Wheelhop. Gain Control.
Upgrade your S550 Mustang’s rear suspension with BMR Suspension’s BK055 Lower Control Arm Spherical Bearing Kit. Designed to replace the factory rubber bushings in the rear lower control arms, this kit eliminates unwanted deflection that leads to wheelhop and sloppy handling—especially under hard acceleration or aggressive cornering.
The factory rubber bushings, while great at absorbing NVH, are prone to flex under load. BMR solves this with 1-inch heavy-duty spherical bearings pressed into machined bearing cups and held in place with robust snap rings. CNC-machined billet aluminum spacers ensure a precise fit for maximum performance in any driving condition.
