1978-1988 Cutlass UMI Stage 3.5 Handling Package, 2 Inch Lowering Springs, Black GBF035-2-B

UMI's Stage 3.5 kit is designed to transform your Cutlass from a grandma 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 Cutlass 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 1/2 inch taller upper ball joints work with the lowering springs to tune up the poor factory Cutlass 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 new pro-tour bar performs on the street, during cornering and even a 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.
