UMI rear lowering springs for 1964–1972 A-Body and 1978–1988 G-Body applications use premium 9254 CrSi wire and a linear 130 lb/in rate to provide consistent handling and reduce body roll. Suited to auto-x, pro-tour and spirited street use, they resist the floating feeling common in older A-bodies, carry a durable black powdercoat and are manufactured in the USA for long-term consistency and ride height control.
