UMI Performance 1968-1972 GM A-Body Adjustable Upper Control Arms- Poly Bushings - 4025-B
UMI’s adjustable rear upper control arms are a bulletproof addition to your street car. UMI’s upper control arms are suitable for street, strip or corner carving. The greaseable polyurethane bushings minimize 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 many applications. 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.
UMI Performance bump steer kits relocate the outer tie rod pivot point which results in decreased toe change during wheel travel. Standard kits include sleeves, rod ends, jam nuts and high quality, direct fit tapered studs. Race kits require drilling of the spindle and include heavy duty 5/8 bolts. Race kits are recommended for autocross and road race applications while standard kits are indicated for street/strip use.
