1993-2002 GM F-Body Complete Coilover Kit, Single Adj., Monotube


UMI’s 4th Gen F-body competition coilover package is built to perform. Developed in conjunction with Sam Strano (14x national SCCA auto-x champion), the Afco built monotube dampers provide race winning performance in auto-x and road race while still providing an awesome street ride. The package includes rebound adjustable dampers with a properly tuned fixed compression valve code. The 40-position digressive rebound curve is designed for competition body and weight transfer control. Spring rates are 600 lb/in front and 200 lb/in rear Hypercoils. These rates and damping curves in conjunction with available 35mm/22mm sway bars encourage race winning performance. UMI’s aluminum body shocks and coilover brackets are race-proven for three seasons now under punishing conditions. Ride height adjustment range is stock to 2-1/2” lowering. Every part of this competition proven package is 100% Made In USA.

UMI’s complete system includes: 4 coilover shocks, 4 springs with proper spring rate, fabricated bolt in mounting brackets and hardware, thrust bearings for each shock and a spanner wrench for height adjustments.
