Provides a Nice Balance When Handling At the Limit

Simple and effective upgrades for real handling improvement

Transform your GM A-Body into a corner-carving machine with UMI’s Stage 3.5 kit. This kit turns your comfortable cruiser into a road-hugging powerhouse with UMI lowering springs and Koni off-car rebound adjustable shocks. The ultra-premium springs, with carefully tuned rates, eliminate the floating feeling, connecting your A-Body directly to the road. UMI A-arms boast tubular construction, Delrin bushings for precise steering, and caster-corrected uppers with ½” taller ball joints to enhance the factory A-body camber curve. In the rear, UMI trailing arms feature Roto-joints for smooth articulation and poly bushings for a comfortable ride. Adjustable uppers enable pinion angle tuning, and the axle-mounted pro-tour bar excels on the street, during corners, and even the occasional dragstrip blast. Designed and manufactured by UMI in Philipsburg, PA, USA, using US materials, this kit reflects our pride in driving and racing what we build.
