UMI lowering kit for 1968–1972 GM A‑Body combines double‑adjustable Viking shocks, a hybrid front coilover system and 1" rear lowering springs to tune ride height and handling. The Viking shocks offer independent compression and rebound adjustment for street, strip or corner carving, while the bolt‑in package requires no welding and allows front drop tuning without a spring compressor when used with the recommended hardware.
