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

UMI’s FBF003 Stage 3 handling kit features everything you need to transform your 2nd Gen F-Body from a land yacht into a modern handling, corner carving muscle car. Caster corrected upper and lower a-arms enhance high speed stability and reduce wandering. These arms feature a tall ball joint in the upper arm and Delrin bushings in the lower to improve steering response and optimize camber gain for better cornering. 2" front lowering springs and rear lowering leafs take away that floating feeling so common with stock, worn out springs. UMI's slim body monotube shocks feature comfortable compression and sporty rebound damping to control body movement and improve response when hitting transitions on your favorite back road. The 2nd Gen platform responds nicely to the heavy duty 1-¼" front sway bar which prevents body roll and makes the car much more fun, and easy, 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, sporty ride. Also included are high quality polyurethane isolator pads as well as heavy duty Made In USA U-bolts and hardware. This kit is suitable for corner carving and even daily driving with a sporty feel. 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.
