UMI Performance 64-72 A-Body Rear Lower Control Arms- Roto-Joint/Roto-Joint

These rear lower control arms from UMI Performance feature Roto-Joint technology, which uses a pivot ball with a greaseable Delrin race. This design allows for up to 28 degrees of unrestricted movement, helping to prevent binding in the suspension. This is a significant improvement over factory rubber or aftermarket polyurethane bushings, allowing your suspension to articulate correctly for more precise handling and a bind-free, low-friction operation. The Delrin race also absorbs shocks and road noise, contributing to a quiet and smooth ride, making them suitable for both street driving and track use.

Constructed from 1.500" x 0.120" DOM mild steel tubing, these control arms are built to last. The Roto-Joints are installed and ready to go, and they are greaseable for low maintenance. The sway bar mounting holes are reinforced with a TIG-welded steel sleeve for added strength. These control arms are designed to fit a wide range of 1964-1972 A-Body vehicles, including popular models like the Chevrolet Chevelle, Pontiac GTO, and Buick Skylark, offering improved performance and suspension travel for your classic car.
