Description
Part #: 203337-B
This kit includes rear lower control arms and an on-car adjustable panhard bar. The control arms have polyurethane bushings on one end and UMI's spherical Roto-Joint on the other. This setup is designed for street performance enthusiasts, with the polyurethane bushings absorbing road noise and shock. The Roto-Joint allows for 28 degrees of total movement, enhancing handling and eliminating rear-end bind. The panhard bar is essential for centering the rear end after lowering the vehicle and accommodating larger tires. It features a CNC-machined double adjuster with left and right-hand threads for easy adjustments without removing the bar. This combination of Roto-Joint and polyurethane bushings improves performance while maintaining ride quality. The kit is made of DOM mild steel tubing, fully TIG welded, and comes fully assembled for easy installation. It utilizes OEM hardware and has a durable powder coat finish. The Roto-Joint technology allows for unrestricted movement, improving traction and reducing wheel hop. The spherical ball rotates in a Delrin race, providing wear resistance and durability. The Roto-Joint is both adjustable and rebuildable, with a spanner wrench available for tightening the adjuster ring or disassembling the joint for maintenance. It is a high-quality addition to any street or drag application.
The UMI Rear End Kit is a direct bolt-on upgrade that improves traction, handling, and overall suspension performance. Ideal for street or track use, it replaces weak factory components with strong, durable tubular parts for lasting results
