A spring is a spring right? Wrong! When UMIchose to manufacture our own line of springs we went all out. Designed inconjunction with a leading Sprint Cup chassis engineer, these springs are thebest in the business. Our springs are wound from 5160 CrSi premiumwire and feature a linear 530 lb/in rate. The 4050F’s are stiffer than stock toprovide increased performance with decreased body roll and a lower center ofgravity. These springs are suitable for Auto-x and Pro-Tour applications as wellas corner carving/cruising. The ride height is engineered for a 1” loweringwith standard SBC, aluminum head and intake Big Block and Pontiac 400 as wellas LS power (lightened cars may require spring trimming). The 4050F’s are alsosuitable for full weight Big Block applications when nose down rake is desired.They have a tough black powder coat finish and UMI proudly manufactures thesepremium quality springs in the USA.
