Stock Height Springs, Coil, Buick, Chevrolet, Oldsmobile, Pontiac, Rear, Pair
UMI Performance stock height springs are designed to add modern handling and a crisp ride while maintaining the factory muscle car appearance. Wound from premium chrome silicon wire, they feature linear rates for consistent handling characteristics with an increase in stiffness to reduce body roll and eliminate the floating feeling so common with factory suspension. Their ride height is engineered to be level on cars equipped with standard small block Chevrolet, Pontiac, aluminum head/intake big block Chevy, or LS engines (lightened cars may require spring trimming). Full-weight big block applications will have a 1/4 in. nose-down rake. Features include: * Designed to maintain the factory muscle car appearance with today's modern feel * Consistent rates and the best materials so your car sits properly for years to come * Linear spring rates provide a firm, yet comfortable, ride and incredible handling * No more floating feeling * Suitable for Pro-Tour, autocross, corner carving, and general cruising * Manufactured in the USA
