UMI Performance 71-80 GM H-Body Adjustable Lower Control Arms - Rod Ends

When you're looking to get the most out of your 1971-1980 GM H-body, like the Chevrolet Vega or Pontiac Sunbird, these adjustable lower control arms from UMI Performance are a solid option. They're designed as a direct bolt-on replacement, meaning you won't need to drill any new holes to get them installed, and they use your car's original hardware. The main job of these arms is to help reduce wheel hop, which is that annoying tendency for your rear tires to bounce under hard acceleration, and to improve overall traction. This makes a big difference when you're pushing your car, whether it's on the track or during an autocross event.

What sets these apart is their adjustability. They feature a Teflon-lined spherical rod end, which allows you to precisely move the rear end forward or backward. This is super handy if you're planning to run larger tires or if you've installed an aftermarket rear end. The arms themselves are constructed from drawn-over-mandrel mild steel tubing, measuring 1.250" OD with a 0.120" wall thickness, and are fully TIG welded for strength. They also incorporate polyurethane bushings, which are bolted to the chassis, to keep things quiet and comfortable during daily driving, while the rod ends connect to the rear end for bind-free operation. The steel sleeves are zinc plated for corrosion resistance, and there are on-car grease fittings so you can keep the rod ends lubricated.
