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, this rear control arm kit is a solid addition to your build. It's designed to minimize suspension deflection, which means crisper handling and less of that annoying wheel hop you can get when accelerating hard.

This kit features fully boxed lower control arms made from 3” x 1-1/2” rectangular tubing. They have CNC machined radius ends that are capped to keep debris out and maintain a clean, factory-like appearance. The upper control arms are built tough with heavy-duty ¼” thick laser-cut mounting pads and feature on-car adjusters. This allows you to easily change your pinion angle for optimal performance, whether you're hitting the street, the strip, or carving corners. All arms are MIG welded and come with greaseable polyurethane bushings and zinc-plated steel sleeves for durability and smooth operation. They're finished with a durable powder coat and are made right here in Philipsburg, PA.

This kit includes everything you need to upgrade your rear suspension. The installation is straightforward, typically taking about 2 hours with basic hand tools. You'll get a more responsive feel from your rear end, making your classic GM handle more predictably.
