UMI Performance 78-88 GM G-Body Adjustable Upper Control Arms- Poly Bushings

Starting with 0.250" thick CNC machined steel mounting plates, these UMI Performance adjustable upper control arms are built solid for your GM G-Body. They allow you to precisely adjust the pinion angle, which is crucial for optimizing handling and traction, especially if you've lowered your vehicle or are running more power. This adjustment can help reduce wheel hop and improve your track times by getting the most grip from your tires.

The adjusters themselves are made from heat-treated 4140 chrome moly, and the threaded tube adapters are also 4140 chrome moly, ensuring strength and durability. A notable feature is the on-car adjuster, meaning you can make changes without having to remove the control arm from the vehicle, saving you time and hassle. These arms come equipped with grease-able, fluted polyurethane bushings from Energy Suspension, which offer a good balance of performance and durability, and are finished with a tough gloss powder coat to resist corrosion.

These control arms fit a range of GM G-Body vehicles from 1978 to 1988, including models like the Chevrolet Monte Carlo and Pontiac Grand Prix. They are a well-built upgrade for anyone looking to fine-tune their suspension for better performance.
