UMI Performance 64-67 GM A-Body Rear Control Arm Kit Boxed Lowers

This UMI Performance rear control arm kit gives your 1964-1967 GM A-Body vehicle a solid upgrade for street driving, drag racing, or spirited cornering. You get a set of boxed lower control arms and fixed-length upper control arms, all assembled with greaseable polyurethane bushings and zinc-plated steel sleeves. The kit is designed to reduce suspension deflection, leading to crisper handling and less wheel hop, especially when you're putting power down. This is a well-built addition that stiffens up your rear suspension setup.

The boxed lower control arms are built tough with 1/8" wall mild steel tubing and feature TIG-welded sleeves that reinforce the sway bar mounting holes. This means you can easily mount a factory-style sway bar, including UMI's popular 1-inch version. The upper control arms use a CNC laser-cut 1/4" thick mounting pad, precision-machined for accuracy and designed to fit all rear end housings. All the bushing holders are MIG welded for strength, and the entire assembly is finished with a durable powder coat for long-lasting protection. UMI machines these arms on CNC equipment for consistent accuracy and assembles them with high-quality, greaseable polyurethane bushings.

This kit is made in Philipsburg, PA, USA. Installation is straightforward, typically taking about two hours with basic hand tools, and it's designed to fit a range of GM A-Body models from 1964-1967, including the Chevrolet Chevelle, Pontiac GTO, and Buick Skylark. It's a popular choice for anyone looking to improve their classic GM's rear suspension performance.
