UMI Performance 64-67 GM A-Body Adjustable Upper & Lower Control Arm Kit

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 vehicle like a Chevelle, GTO, or Skylark, these adjustable upper and lower rear control arms are a significant upgrade over stock. The factory arms can flex and wear out, leading to less predictable handling and traction issues, especially when you're putting power down. These UMI arms are built to address those weaknesses, giving you a more solid connection between your chassis and rear axle.

What sets these apart is the construction: they're made from strong 1.625-inch DOM mild steel tubing, fully welded for durability, and then finished with a tough powder coat. Inside, you'll find on-car greaseable Energy Suspension polyurethane bushings. These bushings are a big step up from the stock rubber ones because they reduce deflection, which helps minimize wheel hop and improves the consistency of your car's handling during cornering. The adjustability also means you can fine-tune your rear suspension alignment for better performance, whether you're cruising or hitting the track.

Installation is designed to be a bolt-on job, using your original hardware, and should take about two hours. UMI includes detailed instructions to guide you through the process. These arms are also compatible with both factory and aftermarket sway bars, making them a versatile addition to your rear suspension setup.
