UMI Performance 1" Lowering Spring Set for 1967-1972 GM A-Body

Achieve the perfect blend of aggressive stance and enhanced performance with the UMI Performance 1-inch lowering spring set, meticulously designed for 1967-1972 GM A-Body vehicles. This comprehensive kit includes both front and rear springs, engineered to provide a balanced, lower center of gravity and improved handling dynamics.

Engineered for Performance and Style:

  • Balanced Lowering: This set provides a 1-inch drop for your vehicle, offering a sportier profile without compromising suspension travel or ride quality excessively.
  • Front Spring Specs: The front springs are precision-wound from durable 5160 CrSi premium wire and feature a linear 530 lb/in rate. This stiffer rate significantly reduces front-end dive and body roll during aggressive maneuvers.
  • Rear Spring Specs: Complementing the front, the rear springs are crafted from 9254 CrSi premium wire with a linear 130 lb/in rate, ensuring a balanced suspension response and preventing the "floating" feel.
  • Versatile Fitment: Engineered to work with common engine configurations like standard SBC, aluminum head Big Blocks, and LS swaps, these springs offer a lowered stance suitable for various powerplants. (Note: Lighter vehicles may benefit from spring trimming.)
  • Application Range: This kit is ideal for a wide array of 1967-1972 GM A-Body models, including Buick Skylark, Chevrolet Chevelle, El Camino, Oldsmobile Cutlass, and Pontiac GTO, as well as compatible 1978-1988 G-Body vehicles.
