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

UMI Performance is known for making well-built suspension components for classic American cars. If you're working on a 1965-1970 Chevrolet Bel Air, Biscayne, Caprice, or Impala, these rear lower control arms are a solid upgrade over the original stamped steel parts. Over time, factory control arms can rust and weaken, while the rubber bushings degrade, leading to a less comfortable ride and reduced performance. These new boxed control arms are designed as a direct bolt-in replacement, meaning you won't need to modify your chassis to install them.

Constructed from strong 1/8-inch wall USA rectangular tubing with DOM bushing holders, these arms are built to last. They come pre-assembled with greaseable polyurethane bushings, which offer a notable improvement over worn-out rubber. Polyurethane bushings reduce deflection, helping to decrease body roll and increase traction, making your classic handle more predictably. UMI also includes the spring perches and clips, so you can use your factory springs or aftermarket lowering springs without issue. Plus, reinforced sway bar holes add to their robust design.

For a cleaner installation, UMI offers an optional hardware kit with Grade 8 hardware, though you will reuse your factory shock mount bolt. These control arms are designed and manufactured in Philipsburg, PA, USA, ensuring solid construction and improved performance for your classic B-body.
