UMI’s F-body front coilover kit enables the installation of a 2-1/2” racing coilover spring and shock in your 93-02 GM F-body. The kit includes a factory-style lower t-bar that fits factory GM, UMI, and most other brands of lower arms designed for stock t-bars. It replaces the factory GM rubber shock mount with a race-proven double shear upper mount that is powder-coated for durability. The UMI-designed upper brackets are compatible with Viking double adjustable coilover-specific shocks and provide a choice of spring rates (300, 350, 450, and 550 lb-in).

The included Viking shocks feature upper and lower bearings for enhanced response and reliability. This kit allows for a 1-3” lowering without making any permanent changes to the upper spring mount or chassis. The Spanner Wrench & Thrust Bearing Kit is available for easier height adjustments but is not necessary for installation. However, using the thrust bearing kit is recommended for simpler adjustments. Adjusting the height on the car without a thrust bearing kit is not advised.
