The UMI Viking front coilover kit for 1970–1981 F‑body and 1978–1996 B‑body uses a hybrid coil spring with a 19‑position double‑adjustable shock to let you dial compression and rebound independently. The threaded adjuster acts as a compressor; ride height adjusts via spanner wrench and thrust bearing. Choose from several spring rates and lower mount styles—polyurethane for smoother street manners or bearing for higher‑stress track applications.
