UMI's tubular lower control arms for the 1982-2002 GM F-Body feature Roto-Joint technology, delivering bind-free performance and a quiet, comfortable ride. The Roto-Joint design allows for 28 degrees of total unrestricted movement, enhancing performance compared to factory rubber and aftermarket polyurethane bushings. This design improves precision handling and permits free movement of the rear end, making it ideal for high-performance driving while remaining street-friendly. The control arm set is made from 1.500” x 0.120” DOM mild steel tubing and includes swivel Roto-Joints with greaseable polyurethane bushings. Fully TIG welded and shipped assembled, these control arms are designed for easy installation using OEM hardware. A durable powder coat finish gives the set a sleek appearance. UMI's Roto-Joint technology combines the performance of a spherical rod end with the comfort of a softer bushing. The Roto-Joint improves traction, reduces wheel hop, and prevents suspension bind. Featuring a 4140 chrome moly spherical ball, hard chrome plated and rotating in a Delrin race, the Roto-Joint is built for durability and wear resistance. Its adjustable and rebuildable design ensures long-lasting performance.
