UMI Performance 78-88 G-Body Boxed Lower Control Arms- w/ Dual Roto-Joints

UMI Performance is known for making well-built suspension components that improve handling. These boxed lower 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 improved traction and reduce wheel hop, making them a solid option for street driving or track use.

These control arms are fabricated from strong 0.120” wall thickness rectangular tubing and feature a boxed construction for added rigidity. UMI's Roto-Joint technology is installed on both ends, offering 28 degrees of movement. This design allows the suspension to articulate freely without binding, which is a significant improvement over factory rubber or aftermarket polyurethane bushings. The Roto-Joints have a delrin liner that absorbs road noise and shock, contributing to a quiet and comfortable ride quality even with their performance focus. They also include reinforced provisions for adding a rear sway bar.

The control arms come fully assembled and ready to install using your OEM hardware. They feature a durable powder coat finish and are MIG and TIG welded for superior strength. The Roto-Joints are greaseable, making them low maintenance for both daily drivers and performance builds.
