UMI Performance 1971-1975 GM H-Body Non-Adjustable Upper Control Arms - 5018-B
UMI Performance’s rear upper control arms for the 1971-1975 GM H-Body are a direct bolt in replacement for the rear factory control arms. The light weight tubular construction is designed to minimize wheel hop, improve traction and help track consistency. The solid construction eliminates flex found in the factory control arm while the new supplied Energy Suspension bushings minimize bushing deflection. UMI’s control arms are fabricated from 1.250” drawn over mandrel mild steel tubing, they are CNC machined and fully TIG welded for the utmost in strength. Control arms also feature grease-able Energy Suspension polyurethane bushings, grease fittings and zinc plated steel sleeves. Adding UMI Performance control arms also add cornering improvements and rear stability to your vehicle while working excellent on both a street car and drag racer. Note: The 1975 Vega Cosworth and other H-Bodies in 1975 used a panhard bar/torque arm set-up. If your vehicle is a 1975 model please verify your vehicle has rear upper control arms.
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.
