UMI Performance 64-72 GM A-Body 78-88 G-Body 1in Lowering Spring Rear

A spring is a spring right? Wrong! When UMI chose to manufacture our own line of springs we went all out. Designed in conjunction with a leading Sprint Cup chassis engineer, these springs are the best in the business. These 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 A-body. These springs are suitable for Auto-x and Pro-Tour applications as well as corner carving/cruising. They have a tough black powder coat finish and UMI proudly manufactures these premium quality springs in the USA.This Part Fits: Year Make Model Submodel 1967 Buick Gran Sport Base 1978-1987 Buick Regal Base 1988 Buick Regal Custom 1982-1983 Buick Regal Estate Wagon 1987 Buick Regal GNX 1984-1987 Buick Regal Grand National 1978-1988 Bu
