Product details
UMI’s 2nd Gen F-Body lowering springs are wound from 5160 CrSi premium wire and feature a linear 600 lb/in rate. UMI’s front springs 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 target 1” lowering with standard SBC as well as LS power (lightened cars may require spring trimming). The front springs are also suitable for full weight big block applications when ¼” additional lowering is desired. They have a tough black powder coat finish and UMI proudly manufactures these premium quality springs in the USA. Consistent rates and only the best materials (premium Chrome Silicon wire) ensure your cars sits properly for years to come. Linear spring rate of 600 lb/in front provides a firm yet comfortable ride and incredible handling. 2647F - 1970-1981 GM F-Body Lowering Spring, Front, 2” Lowering Suitable for Pro-Tour, Auto-x and general cruising.
