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

If you're working on a 1978-1988 G-Body like a Buick Regal, Chevy Monte Carlo, or Pontiac Grand Prix, these lower control arms from UMI Performance are a solid option for improving your suspension. They replace your stock arms with a tubular design that incorporates a unique combination of polyurethane bushings on one end and UMI's Roto-Joint technology on the other. This setup is designed to give you a bind-free performance during spirited driving while still providing a comfortable ride on the street.

The Roto-Joints are the key here. They use a pivot ball with a greaseable Delrin race that allows for a generous amount of articulation, letting your suspension move freely without binding. This is a big improvement over stock rubber or even standard polyurethane bushings, especially if you're looking for more precise handling during auto-cross or road racing. The polyurethane bushings, being a bit softer, are mounted to the chassis side to absorb road noise and shock before it gets into the cabin, making them streetable. These arms are constructed from strong 1.500” x 0.120” DOM mild steel tubing and come fully assembled with Energy Suspension greaseable bushings and the Roto-Joints already installed. They also have reinforced sway bar mounting holes, ready for your stock or aftermarket sway bar.

These control arms are finished with a durable powder coat and use your OEM hardware for installation, making them a straightforward upgrade. They're built to be low maintenance and greaseable, offering a great balance for a street-driven cruiser that sees occasional track time.
