1970-1981 GM F-Body Handling Kit, 2" Lowering, Stage 3.5

1970-1981 Chevrolet Camaro
1970-1981 Pontiac Firebird
(All models)

UMI’s Stage 3.5 handling kit features everything you need to transform your 2nd Gen F-Body from a land yacht into a modern handling, fun to drive corner carver. Viking front hybrid coilovers control attitude and altitude and feature a cornering oriented spring rate as well as 19 damping settings in both compression and rebound. Caster corrected upper and lower a-arms, combined with a tall ball joint in the upper arm, improves caster for stability as well as camber gain for cornering. The 2nd Gen platform responds nicely to the heavy duty 1-5/16" front sway bar which flattens cornering and makes the car much more fun to drive. The UMI designed leafs are delivered with the front bushing installed and the kit includes laser cut shackles with Delrin bushings for a crisp, high performance ride. Also included are high quality polyurethane isolator pads as well as heavy duty Made In USA U-bolts and hardware. The rear suspension damping is handled by Viking double adjustable smooth body shocks with 19 compression and 19 rebound settings and pair nicely with the fronts. This kit is suitable for daily driving as well as corner carving and is 100% Made In USA of USA materials.

Optional hardware kit: Upper and lower a-arm premium quality installation hardware kit. P/N 2602 for 1970-1974 or 2603 for 1975-1981.
