UMI Performance 78-88 G-Body Non Adjustable Upper Control Arms- Roto-Joint

UMI Performance is known for making well-built suspension components for classic American cars. These non-adjustable upper control arms are designed for 1978-1988 G-Body vehicles, like the Buick Regal, Chevrolet Monte Carlo, and Pontiac Grand Prix. They replace your stock control arms to give you a bind-free suspension movement and a more comfortable ride.

The key to these control arms is UMI's Roto-Joint technology. It uses a pivot ball with a greaseable Delrin race that allows for 28 degrees of unrestricted movement. This is a big improvement over factory rubber or aftermarket polyurethane bushings, letting your suspension articulate properly for better handling, especially during aggressive driving like auto-cross or road racing. Even though they improve performance, the Delrin race also absorbs road noise and shock, making them perfectly streetable for your cruiser. Constructed from strong 1.500” x 0.120” DOM tubing with thick 0.250” CNC machined mounting plates, these arms are built to last and are supplied fully assembled and ready for installation.
