Upgrade your GM B-Body Rear Suspension | UMI Performance Adjustable Rear Upper & Lower Control Arms

UMI Performance offers adjustable upper controls that enhance handling performance by reducing wheel hop and increasing traction through a bolt-on installation featuring spherical Roto-Joints. These joints allow for unrestricted movement and improved articulation compared to factory rubber or polyurethane bushings, resulting in precise handling suitable for both street and high-performance driving scenarios.

UMI’s high durometer polyurethane bushings replace the factory rubber rear end housing bushings. After many years of weather and abuse the factory rubber bushings tend to dry rot, crack and harden which can lead to decreased ride quality and performance. The UMI polyurethane bushings replace the two upper control arm rear end differential bushings - the bushings that stay attached to the rear end “ears”. New rear end housing bushings are an excellent upgrade for your street driven or track used vehicle. Kit includes two bushings and two washers, the included polyurethane washers prevent the bushings from walking side to side. Made in the USA.
