| 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.

Rear Bump Stops: We highly recommend running factory rear rubber bump stops in conjunction with the rear coilover kit. If the factory rubber bump stops are damaged or missing replacement part number 2056 is recommended. We do not recommend using polyurethane bump stops.
