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

If you're looking to get the most out of your 1978-1988 G-Body's suspension, especially when pushing it hard in corners or on the track, these rear lower control arms from UMI Performance are a solid choice. They replace your stock arms with a well-built tubular design that incorporates UMI's Roto-Joint technology. This advanced joint allows for a significant amount of unrestricted movement, up to 28 degrees, which means your suspension can articulate freely without binding. This is a big improvement over the stock rubber bushings, which can restrict movement and lead to less precise handling.

The Roto-Joints use a greaseable Delrin race around a spherical ball, which not only allows for that free movement but also absorbs shock and road noise. This means you get the performance benefits for autocross or road racing, but it's still comfortable enough for daily driving on your cruiser. The arms themselves 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 fit a wide range of G-Body vehicles, including models like the Buick Regal, Chevrolet Monte Carlo, and Pontiac Grand Prix, making them a versatile upgrade for many enthusiasts.
