UMI’s bolt-in rear coilover kit allows full ride height, spring rate and damping adjustability for your 1982-2002 Camaro and Firebird. The double shear upper mount is a direct bolt-in and holds a true 2-1/2” racing coilover. The FEA designed lower bracket bolts in using the standard shock mounting hole as well as an additional reinforcement hole. Drilling one 3/8” hole per side is required to complete the installation (no welding). The Viking shock is 19-way adjustable in both compression and rebound and ensures the perfect setting for every application. The 2-1/2” coilover springs are available in 14” 110lb for drag use, 14” 125lb for street use and 12” 150lb for auto-x/road race.

Important notes: The UMI rear coil over kit is a racing oriented kit and may not fit every application. Occasional trimming or component relocation may be required. This kit has been confirmed to clear with UMI 22mm rear sway bar, UMI drag bar and the factory rear end. We have also confirmed this kit to work on Moser Engineering and Strange brand rear ends. One set of 3/16” thk shims are included. Various aftermarket rears may require adjustment.

Spanner Wrench & Thrust Bearing Kit: Spanner wrench tool is used to adjust vehicle height while shock stays mounted. This wrench is needed to make height adjustments. The thrust bearing kit is designed to be placed between the spring and the spring seat attached to the shock. This makes for easier adjustments since the spring seat is rotating on a bearing. This kit is recommended for easier adjustments but is not needed to complete the installation. We do not recommend adjusting height on the car without a thrust bearing kit.
