1967-1972 Chevelle UMI 1 Inch Lowering Coil Spring Kit, Front & Rear 4050

A spring is a spring right? Wrong! When UMI chose to manufacture their own line of Chevelle performance springs they went all out. Designed in conjunction with a leading Sprint Cup chassis engineer, these UMI Performance springs are the best in the business. These UMI Performance springs are wound from 5160 CrSi premium wire and feature a linear 530 lb/in rate. The rear springs are wound from 9254 CrSi premium wire and feature a linear 130 lb/in rate. The linear rate provides consistent handling characteristics which are important for Auto-x and Pro-Tour applications while the increase in stiffness reduces body roll and prevents the floating feeling so common with the Chevelle. These UMI Performance springs are suitable for Auto-x and Pro-Tour applications as well as corner carving/cruising. The ride height is engineered for 1 inch lowering with standard SBC, Pontiac 400, or aluminum head/intake Big Block Chevy as well as LS power (lightened cars may require spring trimming). The front springs are also suitable for full weight Big Block applications when nose down rake is desired. They have a tough, black powder coat finish and UMI proudly manufactures these premium quality springs in the USA.

As an industry leader in the muscle car suspension industry, UMI is proud to bring you the best spring in the business.
