UMI Performance Adjustable Rear Upper Control Arms - Rod Ends - Red (1978-1988 GM G-Body) (3017-R) - 1978-1988
Fine-tune rear pinion angle, maximize launch traction, and eliminate 4-link suspension binding with UMI Performance "Ultimate" Adjustable Rear Upper Control Arms with Spherical Rod Ends (3017-R). Engineered specifically for 1978-1988 GM G-Body platforms—including the Buick Grand National/Regal, Chevrolet Monte Carlo, El Camino, Oldsmobile Cutlass, and Pontiac Grand Prix—these race-ready upper control arms feature an on-car turnbuckle adjuster that lets you set precise pinion angle right at the track or in your garage without unbolting the arms.
Built with aircraft-quality 4140 chromoly steel components, 0.250" CNC-machined steel mounting brackets, and a 1.000" heat-treated solid 4140 chromoly adjuster, UMI "Ultimate Arms" deliver unmatched yield strength and rigidity. Equipped with self-lubricating, Teflon/Kevlar-lined QA1 3/4" hard chrome rod ends and CNC-machined 6061 aluminum step bushings, these control arms articulate completely bind-free through full suspension travel. Adjusting pinion angle reduces 60-foot times, optimizes driveshaft angle, and prevents violent wheel hop under heavy drag racing or high-g autocross cornering. Finished in a vibrant red powder coat, this direct bolt-on set installs using factory mounting hardware.
