Coil Springs, UMI Perf. Rears - 130LB, 1967-72 A-Body

UMI Is Proud To Bring You The Best

No more floating feeling

UMI has transformed spring manufacturing, teaming up with a leading Sprint Cup chassis engineer for outstanding results. Our front springs, crafted from top-notch 5160 Chrome Silicone wire, offer a linear 530 lb/in rate, while the rear springs, wound from 9254 CrSi wire, feature a linear 130 lb/in rate. These linear rates ensure consistent handling, perfect for Auto-x and Pro-Tour applications, minimizing body roll and eliminating the "floating" feeling. Proudly made in the USA, these premium springs are topped with a durable black powder coat. Each of these spring height options have been specifically engineered for standard Small Blocks, aluminum head/intake Big Blocks, 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” nose down rake is desired.
