Have a high Horsepower Mustang? Trying to get the most traction with a factory style suspension? These billet Spherical Upper Control Arm Bearings are what you need when trying to apply high horsepower to the back tires of your 1979-2004 Mustang. They have been proven in 7-second Mustangs cutting 1.1 sixty foot times!!! The upper control arms are under a tremendous amount of stress as their job is to try and lift the front of the car to transfer as much weight as possible to the back tires. The factory rubber and aftermarket urethane bushings will deflect and cause a drastic change in pinion angle which isn't a desirable situation. Made in the USA from 6061 Billet aluminum, these housings simply screw together once installed in the Ford 8.8 rear end. Billet Aluminum spacers are pressed into high-quality COM12 bearings. Finishing things off is a 360-degree spiral lock that secures the COM12 bearing in place. Lifetime warranty.
