They can be used for street, drag race, road race and autocross applications. Spherical aircraft bearings on the frame side and a Del-A-Lum bushing on the rear end side. Good for street, road race and drag strip. This lower control arm design performs flawlessly. The maintenance is low and the bushings are quiet. The rear end is stable especially around corners. The arm allows the rear end to pivot without bind due to the bearing being installed on the frame side. Del-A-Lum bushings provide lateral control. This feature will make the car track straighter during a drag launch plus increased lateral cornering ability is achieved. The Del-A-Lum bushings have a lifetime warranty to the original purchaser.
These bearing kits eliminates using rubber or polyurethane bushings in the upper pivot location. No modification to the rear end housing is required. Sold in Pairs
