The UMI Viking front coilover kit for 1968–1972 GM A‑body pairs a hybrid coil spring with a 19‑position double‑adjustable Viking shock to give independent compression and rebound tuning. The threaded adjuster compresses the spring so no separate compressor is required; a spanner wrench and optional thrust bearing let you set ride height up to 3" lower. Choose polyurethane or bearing lower mounts and front spring rates from 250–550 lb; shocks are dyno‑tested and rebuildable in the USA.
