UMI Performance 4050F Front Lowering Springs, 1-inch Drop, 530 lb/in for Select 1967-1972 GM A-Body

Fits select 1967-1972 GM A-Body models including Chevrolet Chevelle, El Camino, Monte Carlo, Oldsmobile Cutlass, 442, Buick Skylark, and Pontiac GTO/Tempest.

Designed in conjunction with a leading Sprint Cup chassis engineer, the UMI Performance 4050F front lowering springs are engineered to improve handling and stance without sacrificing ride quality. These springs feature a 530 lb/in linear rate, providing increased stiffness over stock components to reduce body roll and lower the vehicle's center of gravity. Whether you are building a Pro-Touring machine, an autocross competitor, or a refined street cruiser, these springs deliver the performance and durability required for aggressive driving.

The 4050F springs provide a 1-inch drop for vehicles equipped with a Small Block Chevy (SBC), aluminum-head Big Block Chevy (BBC), Pontiac 400, or LS-series engines. They can also be used on full-weight Big Block applications to achieve a more aggressive nose-down rake. Each spring is wound from premium 5160 CrSi wire and finished in a durable black powder coat for long-lasting corrosion resistance.
