UMI Performance 1967-1972 GM A-Body Rear Coil Springs - Factory Height 130 lb/in Linear Rate (4049R)

Fits select 1967-1972 GM A-Body vehicles including Buick Skylark/Special, Chevrolet Chevelle/El Camino, Oldsmobile 442/Cutlass/F85, and Pontiac GTO/LeMans.

UMI Performance rear coil springs are engineered to modernize the handling and ride quality of your classic GM A-body while maintaining its authentic factory muscle car stance. Developed in conjunction with a leading Sprint Cup chassis engineer, these springs replace soft or sagging original equipment to eliminate the "floating" feeling and reduce body roll. The 130 lb/in linear spring rate provides consistent, predictable handling characteristics across the entire range of compression, making them an excellent choice for Pro-Touring builds, Auto-X, and spirited street cruising.

Each spring is manufactured in the USA from premium 9254 Chromium Silicon (CrSi) wire to ensure high tensile strength and long-term resistance to spring fatigue. The coils are finished in a durable black powder coat for superior corrosion resistance and a clean look in the rear suspension assembly.
