UPR Products 78-88 G-body Extreme Series Double Adjustable Uppers

UPR Products 1978-1988 G-Body Extreme Series Double Adjustable Upper Control Arms

Built for the most demanding drag racing and high-horsepower G-Body combinations, the UPR Products Extreme Series Double Adjustable Upper Control Arms deliver unmatched strength, durability, and suspension adjustability. Engineered to withstand the abuse of modern radial tire and outlaw race cars producing over 2,500 horsepower, these control arms feature reinforced chromoly construction and premium hardware for maximum reliability both on the street and at the track.

Each control arm utilizes reinforced chromoly formed boxes with integrated gussets and additional upper and lower bracket reinforcement to eliminate flex under extreme loads. Precision CNC-machined 4130 chromoly threaded adjusters allow pinion angle to be adjusted directly on the vehicle in minutes, making between-round suspension tuning quick and simple. Finished in a corrosion-resistant silver zinc coating and assembled with premium 7075 billet aluminum bushings, the Extreme Series package includes upgraded stainless steel sleeves and large 1/2-inch Grade 8 hardware for maximum strength in the harshest racing environments.
