Product Details
When you're rebuilding the front suspension on your classic GM A-Body, like a 1964-1972 Buick Skylark or a 1970-1972 Chevrolet Monte Carlo, replacing those worn-out stamped steel control arms is a big step toward modernizing its feel. This complete kit from UMI Performance gives you both the upper and lower tubular A-arms, ready to bolt on and significantly improve your car's handling and steering response. It's designed to make your classic feel more connected to the road, like a modern muscle car.
What you get in this kit are fully assembled tubular A-arms, built with strong DOM tubing that's TIG welded for extra durability and a clean look. UMI builds their own Delrin bushings in-house, which are known for their precise handling and smooth suspension movement, and they're greaseable to keep things working right for a long time. The lower arms include polyurethane spring isolators for a bit of comfort, and the ball joint mounts are slightly angled to help with clearance on lowered vehicles. The upper arms have a relocated mounting pad that increases caster without needing a stack of shims, improving steering feel. Both arms come pre-assembled with new, premium ball joints and are jig-built to ensure they fit right every time. This kit is designed to work with your factory springs, lowering springs, or even popular coil-over setups like QA1.
This kit comes with a hardware kit (Part # 4004) that includes Grade 8 bolts, washers, and nylock nuts to replace your old fasteners. You'll also receive recommended alignment specifications and detailed installation instructions to guide you through the process. UMI Performance manufactures these A-arms with pride in Philipsburg, PA, USA, and they are available in a durable glossy red or black powder coat finish.
