Product Summary Buick, Chevy, Oldsmobile, Pontiac, Powder Coated Details UMI’s Stage 3.5 kit is designed to transform your GM A-Body from a comfortable cruiser to a capable corner carver with the twist of the wrist. UMI’s lowering springs form the handling foundation and are controlled by UMI’s premium rebound adjustable shocks. Our ultra-premium springs feature carefully tuned rates and high quality construction to eliminate the floating feeling and will tie your A-body directly to the road. The UMI monotube shocks rebound adjustment allows you to fine tune your ride whether you’re doing back road heroics or shaving that last tenth of a second between the cones. UMI a-arms feature tubular construction, Delrin bushings for precise steering and caster corrected uppers. The ½” taller upper ball joints work with the lowering springs to tune up the poor factory A-body camber curve. Out back the UMI trailing arms feature Roto-Joints for smooth articulation combined with poly bushings for a smooth ride. Adjustable uppers allow for pinion angle tuning while the axle mounted pro-tour bar performs on the street, during cornering and even the occasional dragstrip blast. The entire package is designed and manufactured by UMI in Philipsburg, PA – USA of US materials and we’re proud to drive on and race what we build. Roto-Joints allow smooth articulation for improved handling and less bind. 1” diameter rear Pro-Tour sway bar offers tune-able rear roll resistance and less binding for street, corner carving or light drag and is balanced well with our 1-1/4” front bar and spring rates. Entire kit is designed and built in the USA.
