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

If you're working on a 1978-1988 G-Body vehicle like a Buick Regal, Chevrolet Monte Carlo, or Pontiac Grand Prix, these non-adjustable upper control arms from UMI Performance are a solid option for improving your suspension's performance. They replace the factory rubber bushings with UMI's Roto-Joint technology, which is designed to allow for more suspension articulation without binding. This means your suspension can move more freely, especially during aggressive driving like auto-cross or road racing, while still providing a comfortable and quiet ride on the street.

The Roto-Joints themselves feature a pivot ball lined with a greaseable Delrin race, offering up to 28 degrees of unrestricted movement. This design helps absorb road noise and shock, contributing to a smoother operation. Built from strong 1.500” x 0.120” DOM tubing and featuring .250” thick CNC machined mounting plates, these control arms are well-built for durability. They come fully assembled with the Roto-Joints installed, ready for a direct bolt-on installation using your vehicle's original hardware. Expect improved cornering, better tracking, and reduced wheel hop with these installed.
