1967-1972 GM A-body UMI 2 Inch Lowering Coil Spring Kit, Front & Rear

Product May Vary From Above Listed Image

A spring is a spring right? Wrong! When UMI chose to manufacture their own line of GM A-Body coil 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 front 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 GM A-Body. 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 2 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 1/4 inch 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.

  • Consistent rates and only the best materials (premium Chrome Silicon wire) ensure your cars sits properly for years to come.
  • Linear spring rates (530 lb/in front, 130 lb/in rear) provides a firm yet comfortable ride and incredible handling.
  • No more floating feeling.
  • Suitable for Pro-Tour, Auto-x and general cruising.
  • 2 inch Lowering with standard SBC, Pontiac 400 and aluminum head/intake Big Block Chevy as well as LS power.
