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

UMI Performance is known for making well-built suspension components for classic American cars. If you're working on a 1964-1967 GM A-Body, like a Chevelle, GTO, or Skylark, and want to tighten up the rear suspension, this control arm kit is a solid choice. It's designed to minimize suspension deflection, which helps reduce wheel hop during hard launches and improves overall handling for street driving, drag strip use, or spirited cornering.

This kit features fully boxed lower control arms made from 3" x 1-1/2" rectangular tubing. The ends are capped to keep debris out and maintain a clean, factory-like appearance. The upper control arms are built tough with heavy-duty 1/4" thick laser-cut mounting pads that fit various rear end housings. They also include on-car adjusters with CrMo and Teflon-lined rod ends, offering smooth suspension articulation with less friction and improved performance during aggressive driving. All arms are MIG welded and CNC machined for accuracy, then finished with a durable powder coat. The kit includes greaseable polyurethane bushings with zinc-plated steel sleeves for longevity.

This kit is designed to be a direct bolt-on replacement for your stock control arms, making installation straightforward. It typically takes about 2 hours to install using basic hand tools. You'll get a more responsive feel from your rear suspension, especially when you're putting the power down.
