1978-1987 Regal UMI 1 Inch Lowering Springs, Rear 4050R

A spring is a spring right? Wrong! When UMI chose to manufacture their own line of Regalcoil 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 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 and Regal, Regal, Monte Carlo, Regal, Grand National, Regal, 442, or Regal. These UMI Performance 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.

As an industry leader in the muscle car suspension industry, UMI is proud to bring you the best spring in the business.
