UMI Performance 91-96 Impala SS Adjustable Extended Length Upper Control Arms - Roto-Joints - 3624-B

Eliminate wheel hop, increase traction and improve handling performance with an easy bolt on installation. UMI Performance’s adjustable upper controls feature on car adjustability and are supplied with spherical Roto-Joints. The Roto-Joint design is a pivot ball lined with a greaseable delrin race designed to offer 28 degrees of total unrestricted movement, more than adequate for a bind free, low friction operation. The Roto-Joint design improves performance over the factory rubber and aftermarket polyurethane bushings by allowing the suspension to articulate correctly, and provide precision handling. The installed UMI Roto-Joint allows rear end free movement when high handling, auto cross or road race is a concern while still being a 100% streetable setup. The installed delrin race, which lines the spherical ball, absorbs shock and road noise for a quiet and smooth operation on any street or track driven vehicle.
