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

If you're looking to firm up the rear suspension on your classic GM A-Body, this UMI Performance rear control arm kit is a solid addition. Designed for 1964-1967 models like the Chevelle, GTO, Skylark, and Cutlass, this kit aims to reduce suspension deflection. This means less wheel hop during hard launches and a more responsive feel when you're cornering, whether you're cruising the street or hitting the strip.

The kit features fully boxed lower control arms built from 3” x 1-1/2” rectangular tubing. These arms have CNC machined radius ends that are capped to keep debris out, maintaining a clean factory look. The upper control arms are built tough with heavy-duty ¼” thick laser-cut mounting pads and feature on-car adjustability using CrMo adjusters and Teflon-lined rod ends. These rod ends allow for suspension articulation while acting like a solid bushing, reducing friction for better performance during harder launches. All arms are MIG welded and come with greaseable polyurethane bushings and zinc-plated steel sleeves for durability.

This kit is designed for a direct fit and installs using basic hand tools, typically taking around 2 hours. The durable powder coat finish helps protect the arms from the elements, and they are proudly made in the USA.
