Product Details
The UMI Performance 1964-1966 GM A-Body 1in rear lowering spring set uses chrome silicon wire with a linear 130 lb/in rate to lower the rear by 1 inches, which firms up the ride and reduces body roll on this chassis.
A spring is a spring right? Wrong! When UMI chose to manufacture our own line of springs we went all out. 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 A-body. These springs are suitable for Auto-x and Pro-Tour applications as well as corner carving/cruising.
