Minimize wheelhop and enhance the rear stability of your 2015 and newer S550 Mustang by eliminating rear lower control arm bushing deflection with a set of Lower Control Arm Spherical Bearings from BMR Suspension. The stock rubber bushings are great for absorbing NVH, but do little for performance. The large spherical bearings in BMR?s rear Lower Control Arm Spherical Bearing Kit simply eliminate bushing deflection, transferring power instead of absorbing it. BMR Suspension?s rear Lower Control Arm Spherical Bushings (BK055) drastically decreases lower control arm movement by eliminating deflection of the factory rubber bushings. BMR uses heavy-duty 1-inch spherical bearings in machined bearing cups to replace the factory rubber bushings. The cup and bearing press into the lower control arm and are held in place with heavy-duty snap rings. CNC-machined billet aluminum spacers complete the assembly. This allows for a perfect fit and increased performance for any driving style.
