Description

UMI's Stage 5 kit is designed for Pro-Touring Chevelles, transforming them into corner-carving machines. The front features UMI's 4056-3 adjustable a-arms with 0.9-inch taller upper ball joints and 0.5-inch taller lower ball joints, increasing spindle height by 1.4 inches for improved camber gain, caster, and reduced bump steer. These lower a-arms use UMI-built Delrin bushings. Viking's front hybrid coilovers offer double-adjustable compression and rebound (361 combinations) and ride height adjustment. A 1.250-inch CrMo front handling sway bar completes the front. The rear includes adjustable tubular frame braces, double Roto-Joint lower trailing arms, fully adjustable Roto-Joint upper control arms, and 2999 axle housing Roto-Joints for full articulation. 1-inch UMI rear lowering springs are paired with Viking's double-adjustable rear shocks (361 combinations). A three-way adjustable 1-inch tubular Pro-Tour rear sway bar attaches to the axle and crossmember (requires drilling four 3/8-inch holes). All components are manufactured in Philipsburg, PA, USA.
