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

The fully boxed lower control arms in this UMI Performance kit are built from substantial 3” x 1-1/2” rectangular tubing, featuring CNC machined radius ends with capped openings to keep debris out and maintain a clean, factory-like appearance. This robust construction is designed to minimize suspension deflection, which translates to crisper handling and less wheel hop, whether you're cruising the street, hitting the drag strip, or carving corners. This kit is a solid addition for your 1964-1967 GM A-Body vehicle, including popular models like the Chevrolet Chevelle, Pontiac GTO, and Buick Skylark.

Complementing the strong lowers, the heavy-duty upper control arms offer on-car adjustability. This feature is crucial for making quick and easy pinion angle changes, allowing you to fine-tune your setup for maximum performance. The upper arms use durable ¼” thick laser-cut mounting pads, engineered to work with various rear end housings. UMI machines these control arms with precision for accuracy and consistency, assembling them with greaseable polyurethane bushings and zinc-plated steel sleeves for long-lasting, comfortable operation. The entire assembly is finished with a durable powder coat for longevity.

This kit is MIG welded and assembled in Philipsburg, PA, USA. Installation is straightforward, typically taking about 2 hours with basic hand tools, as it utilizes direct bolt-on mounting points. You'll find that the combination of strong materials, thoughtful design, and precise manufacturing makes this a worthwhile upgrade for your classic GM A-Body.
