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

Take the rear suspension of your G-Body to the next level with the UPR Products Pro-Series Double Adjustable Upper Control Arms. Designed for serious street, drag racing, and high-horsepower applications, these heavy-duty upper control arms feature reinforced chromoly construction, double-adjustable geometry, and premium billet components that allow precise pinion angle adjustments without removing the control arms from the vehicle.

Constructed from heat-treated steel with reinforced chromoly formed boxes and additional upper and lower bracket reinforcement, these control arms are engineered to withstand extreme abuse from today's highest horsepower combinations. The CNC-machined 4130 chromoly threaded adjusters make on-car pinion angle adjustments quick and simple, while 7075 billet aluminum bushings provide exceptional strength and durability. Finished in a corrosion-resistant silver zinc coating, each set is fully TIG welded using billet steel fixtures for maximum precision and consistency.
