# UMI Performance 82-02 GM F-Body On-car Adjustable Control Arms- Poly/Roto-Joint

UMI's on car adjustable lower control arms utilize our Roto-Joint technology for a bind free performance, quiet ride quality, and also offer on car adjustment. The control arms can be adjusted longer or shorter moving the rear end back or forward to accommodate larger tires in the fender wells. Adjustable control arms are also recommended for aftermarket rear end installs to center the rear end and prevent tire rubbing. The installed Roto-Joint is a pivot ball lined with a greaseable delrin race designed to offer 28 degrees of total unrestricted movement, improving performance and providing precision handling. The Chrome Moly version uses 1.250" x 0.095" 4130 Chrome Moly steel for increased strength and reduced weight. UMI's Roto-Joint allows 28 degrees of total rotation and unrestricted movement throughout the vehicle's suspension, preventing bind and improving traction. The Roto-Joint features a 4140 chrome moly, hard chrome plated spherical ball rotating in a delrin race for wear resistance and durability. The Roto-Joint is adjustable and rebuildable, ensuring longevity and performance. The spanner wrench is used for adjusting and disassembling Roto-Joints for maintenance and rebuilding.
