UMI Performance 65-70 GM B-Body Rear Lower Control Arms/Trailing Arms

If you're restoring a classic 1965-1970 Chevrolet B-body, whether it's a street cruiser or a drag car, upgrading the rear lower control arms is a smart move. The factory stamped arms can rust and weaken over time, and their original bushings often become brittle and cracked, hurting both ride quality and how the car handles. These boxed control arms from UMI Performance are built to directly bolt in, replacing those tired stock parts with a much stronger setup.

These UMI control arms are constructed from 1/8-inch wall USA rectangular tubing, featuring DOM bushing holders and reinforced sway bar holes for added durability. They come pre-assembled with greaseable polyurethane bushings, which offer a noticeable improvement over worn-out rubber. Polyurethane bushings reduce unwanted flex, helping to decrease body roll and put more power to the ground for better traction. Plus, they include spring perches and clips, so they're ready to accept your factory springs or any lowering springs you might choose.

UMI Performance designs and manufactures these control arms in Philipsburg, PA, USA. An optional hardware kit is available, which includes all the necessary Grade 8 hardware for installation, though you will reuse your original shock mount bolts. This upgrade is a solid way to improve your classic Chevy's handling and longevity.
