Product Description

The UMI Performance 4051R Rear Lowering Springs are designed to lower the rear suspension by approximately 2 inches on classic General Motors A-Body and G-Body vehicles while maintaining ride quality and enhancing handling. These springs use a premium Chrome Silicon construction with a linear 130 lb/in rate to provide consistent performance through aggressive street driving, auto-cross, and pro-tour use.

Built with a tough black powder-coat finish to resist corrosion and increase longevity, the 4051R springs eliminate the common rear "floating" feel on lifted or worn stock suspension. They are engineered for direct bolt-in fitment on RWD Buick, Chevrolet, Oldsmobile, and Pontiac A-Body and G-Body platforms from 1967 to 1972 and 1978 to 1988. Ideal for enthusiasts looking to improve their vehicle's stance, cornering response, and overall stability without compromising comfort.
