Product Details

If you're looking to get a better grip and more stable handling from your classic GM G-Body, upgrading the rear lower control arms is a smart move. The stock arms on these cars can flex and rust over time, which really hurts traction, especially when you're pushing the car a bit harder, whether that's for weekend cruising or some spirited driving. These boxed control arms from UMI Performance are built to address those issues head-on.

What sets these apart is the construction: they're made from strong 0.120-inch wall thickness rectangular steel tubing and feature MIG-welded end caps to keep road debris out. Inside, you'll find grease-able polyurethane bushings that offer a noticeable improvement over the stock rubber ones. They're designed to be a direct bolt-on replacement, using your original hardware, and they're built to minimize that annoying wheel hop you can get from a stock setup. Plus, they've even reinforced the mounting points for sway bars, whether you're running a stock one or an aftermarket unit.

These control arms fit a wide range of GM G-Body vehicles from 1978 through 1988, including popular models like the Chevrolet Monte Carlo and Pontiac Grand Prix. They're a solid option for anyone wanting to improve their car's cornering ability and overall track consistency.
