UMI Performance 73-77 GM A-Body 78-88 G-Body Rear Upper Control Arms Adjustable

UMI’s Roto-Joint adjustable rear upper control arms are a bulletproof addition to your street or pro-touring car. UMI’s Roto-Joint upper control arms are suitable for street, strip or corner carving. The premium UMI built spherical joint drastically minimizes suspension deflection for a crisp handling setup, easy pinion angle tuning and less wheel hop. These on car adjustable upper control arms adjust easily while staying bolted to the car and are designed to handle virtually any application. The Roto-Joints combined with UMI’s in house designed and machined CrMo adjuster equal ultimate strength and performance. These heavy duty arms feature ¼” thick CNC laser cut mounting pads and a mix of TIG and MIG welding. These simple bolt in replacements install in 1-2 hours and are designed to work on all rear end housings. Launch harder and turn faster with UMI’s ultimate arms!
