UMI Performance 78-88 GM G-Body Rear Control Arm Kit Fully Boxed Lowers

If you're working on a 1978-1988 GM G-Body like a Buick Regal, Chevrolet Monte Carlo, or Pontiac Grand Prix, and you're looking to improve how the rear end hooks up, this UMI Performance rear control arm kit is a solid choice. This kit replaces both your stock rear upper and lower control arms, aiming to cut down on traction loss and minimize that annoying wheel hop you can get when the stock arms can't keep up.

The lower control arms in this kit are fully boxed, which means they're built with extra reinforcement for added strength and stiffness compared to the factory tubular arms. This extra rigidity helps keep your rear suspension geometry more consistent under load. UMI designed these arms to be fixed length, matching the factory specifications to ensure a direct fit without altering your wheelbase. They've also reinforced the sway bar mounting holes on the lower arms, so you can confidently use your stock or aftermarket sway bar for better body control.

This kit includes a set of the fully boxed lower control arms and a set of tubular upper control arms. By upgrading these key suspension components, you're setting your G-Body up for improved performance off the line and a more stable feel during spirited driving. When installing, you'll want to refer to the manufacturer's instructions for the proper procedure and any specific torque recommendations.
