UMI Performance 68-72 GM A-Body Adjustable Upper Control Arms- Poly Bushings

Starting with the 4140 chrome moly threaded tube adapters, these UMI Performance adjustable upper control arms are built to handle performance driving. They are designed to optimize your vehicle's performance by allowing you to adjust the pinion angle, which is crucial for reducing wheel hop, increasing traction, and improving your 60-foot times, especially if you're hitting the track. This part fits a variety of GM A-Body vehicles from the mid-60s to early 70s, including models like the Chevrolet Chevelle, Pontiac GTO, and Buick Skylark.

These control arms are well-built with precision CNC machining and fully welded construction. The adjusters are made from heat-treated 1.000" 4140 chrome moly, and the threaded tube adapters are also 4140 chrome moly. A unique feature is the on-car adjuster, meaning you can make adjustments without removing the control arm from your vehicle, simplifying the tuning process. They come equipped with grease-able, fluted polyurethane bushings and CNC machined 6061 aluminum step bushings, along with a durable powder coat finish to resist corrosion.
