UMI Performance 1973-1977 GM A-Body Upper & Lower Control Arm Kit - ABR301-B
UMI’s rear control arm kit is a bulletproof addition to your car. Suitable for street, strip or corner carving, this kit minimizes suspension deflection for a crisp handling setup and less wheel hop. The boxed lower control arms feature reinforced sway bar mounting holes to allow factory style sway bar mounting while the included shim allows the sway bar to sit at factory height. The upper fixed length control arms feature a heavy duty ¼” thick laser cut mounting pads designed to work on all rear end housings. The included polyurethane rear end housing bushings press into the rear end “ears” replacing the worn out factory rubber bushings. The new control arms attach in place using the supplied Grade 8 mounting hardware and Ny-lock nuts. UMI’s control arms are CNC machined for accuracy and assembled with high quality greaseable polyurethane bushings.
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.
