The UMI Performance spring and shock kit for 1978–1988 GM G-Body models lowers the car 2 inches while improving handling and control. Springs use premium CrSi wire and are tuned with ramped rebound valving; monotube shocks are nitrogen-charged for greater control. Complete US-made kit delivers a performance-oriented ride—intended for small-block engines; full-weight big blocks may increase front drop and LS applications may need trimming.
