UMI Performance 78-87 GM G-Body Adjustable Upper Control Arms - Ultimate Arms

When you're tuning the suspension on your street car, adjustability is key. UMI Performance developed these Ultimate adjustable upper control arms specifically for the rear of GM G-Body vehicles from 1978 to 1988. They're built to handle the demands of a tuned suspension, replacing known weak points in stock components with stronger materials.

These arms feature a robust construction using aircraft-quality 4140 chromoly steel for the threaded tube adapters and heat-treated adjusters. The TIG-welded construction ensures solid joints, and the mounting points are precisely CNC machined. For smooth operation and durability, they incorporate QA1 3/4" hard chrome-plated, Teflon/Kevlar self-lubricating race rod ends. The CNC machined 6061 aluminum step bushings add to the well-built nature of these arms, making them a solid option for dialing in your G-Body's handling.

These control arms are designed for on-car adjustability, allowing you to make changes without removing them. They fit a range of popular GM G-Body models, including the Buick Regal, Chevrolet Monte Carlo, and Pontiac Grand Prix, among others. A durable powder coat finish helps protect the components.
