UMI Performance 78-88 G-Body Rear Lower Control Arms- Roto-Joint/Roto-Joint

If you're working on a 1978-1988 G-Body vehicle like a Buick Regal, Chevy Monte Carlo, or Pontiac Grand Prix, and you're looking to improve your rear suspension's performance, these rear lower control arms from UMI Performance are a solid option. They replace your stock arms and use UMI's Roto-Joint technology, which is designed to give you a bind-free range of motion for better handling, whether you're on the street or the track.

The Roto-Joints feature a pivot ball with a Delrin race that allows for up to 28 degrees of movement. This is more than the factory rubber bushings can offer, helping your suspension articulate correctly for more precise steering and a smoother ride. The Delrin material also helps absorb shock and road noise, so you get improved performance without sacrificing comfort. These arms are constructed from 1.500-inch x 0.120-inch DOM mild steel tubing and are fully TIG welded for strength. They also include reinforced sway bar mounting holes, ready for stock or aftermarket sway bars.

These control arms come fully assembled and ready to install using your OEM hardware. They're finished with a durable powder coat and the Roto-Joints are greaseable for low maintenance, making them a great choice for both daily drivers and performance builds.
