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

If you're working on a 1964-1967 GM A-Body like a Chevelle, GTO, or Skylark and want to improve how the rear end handles under acceleration, this UMI Performance Rear Control Arm Kit is a solid choice. This kit replaces both your stock rear upper and lower control arms with fully boxed lower arms and tubular upper arms. The main goal here is to reduce traction loss and minimize that annoying wheel hop you can get when you put the power down, especially with a more powerful engine or sticky tires.

UMI builds these control arms to be fixed length, matching the factory specifications to ensure a direct fit without altering your suspension geometry. The lower control arms are fully boxed for added strength and feature reinforced sway bar mounting holes, so you can easily bolt up your stock or an aftermarket rear sway bar. This attention to detail means you're getting a well-built component designed to handle the stresses of spirited driving and hard launches. The tubular upper control arms complement the boxed lowers, providing a balanced upgrade for the entire rear suspension linkage.

This kit includes a set of boxed lower control arms and a set of tubular upper control arms, giving you a complete rear control arm replacement. When installing, you'll want to refer to the manufacturer's instructions for the proper procedure, but generally, these are designed as a direct bolt-on replacement for your factory arms. Upgrading your rear control arms is a key step in putting down power effectively and improving the overall feel of your classic GM muscle car.
