UMI Performance 64-72 GM A-Body 2in Lowering Spring Set Front

A spring is a spring right? Wrong! When UMI chose to manufacture our own line of springs we went all out. Designed in conjunction with a leading Sprint Cup chassis engineer, these springs are the best in the business. Our springs are wound from 5160 CrSi premium wire and feature a linear 530 lb/in rate. The 4050Fa**s are stiffer than stock to provide increased performance with decreased body roll and a lower center of gravity. These springs are suitable for Auto-x and Pro-Tour applications as well as corner carving/cruising. The ride height is engineered for a 2a*? lowering with standard SBC, aluminum head and intake Big Block and Pontiac 400 as well as LS power (lightened cars may require spring trimming). The 4050Fa**s are also suitable for full weight Big Block applications when A?a*? nose down rake is desired. They have a tough black powder coat finish and UMI proudly manufactures these premium quality springs in the USA. Fitment: Buick Gran Sport Base 1967 Buick Skyla
