UMI Performance 1967 GM A-Body Stage 3.5 Handling Kit 2in Lowering - Red

ABF406-67-2-R

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 shock. UMI’s lowering springs form the handling foundation and are controlled by Koni off-car 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. 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.

Installation notes: SBC, Pontiac 400 or BBC with aluminum heads and intake tend to sit level with this kit. Lightweight LS may require spring trimming. An additional 1/4″ drop may occur on vehicles with all cast iron full weight big block engines or power adders.
