The UMI Performance lowering kit for 1968–1972 GM A‑Body cars combines hybrid front coil‑over springs with four Viking double‑adjustable shocks to let you dial ride height and handling. It offers 0–3" front drop and 1–2" rear lowering choices plus multiple spring rate options. Double‑adjustable shocks provide independent compression and rebound tuning while bolt‑in installation avoids welding.
