UMI Performance 78-88 GM G-Body Rear Lower Control Arms Boxed

If you're working on a 1978-1988 GM G-Body like a Regal, Monte Carlo, or Grand Prix, these boxed rear lower control arms from UMI Performance are a solid addition to your suspension. They're built to reduce how much the suspension deflects, which means crisper handling and less of that annoying wheel hop you can get when accelerating hard or driving spiritedly.

These control arms are constructed from 2” x 1-1/2” x 1/8” wall mild steel tubing and are MIG welded with heavy-duty bushing holders for strength. UMI also reinforces the sway bar mounting holes with TIG welded sleeves, so you can still use your factory sway bar or UMI's own 1-inch version. They come assembled with greaseable polyurethane bushings and a durable powder coat finish, all CNC machined for accuracy and consistency right here in the USA.

Installation is straightforward, typically taking about an hour with basic hand tools, and they're designed to fit right into your G-Body's existing setup.
