UMI Performance 67-72 GM A-Body Spring Kit 2in Lowering

UMI Performance is well-known for making solid suspension parts for muscle cars. If you're looking to give your classic GM A-body a sportier stance and more responsive feel, this spring kit is a great option. It's designed to lower your car by about 2 inches, which not only looks good but also helps reduce body roll and that common floating sensation these cars can have.

These aren't just any springs; UMI worked with a chassis engineer to get the rates just right. The front springs use 5160 Chrome Silicon wire with a linear rate of 530 lb/in, while the rear springs use 9254 Chrome Silicon wire at 130 lb/in. This linear rate means consistent handling, which is beneficial whether you're hitting an autocross course, doing some spirited driving, or just cruising. The springs are finished with a tough black powder coat to protect them and are made right here in the USA.

This kit is designed to fit a wide range of GM A-body vehicles from 1967 to 1972, including popular models like the Chevrolet Chevelle, Buick Skylark, and Pontiac GTO. The 2-inch drop is calibrated for common engine setups like a standard SBC, Pontiac 400, or LS power. If you're running a lighter car, you might need to trim the springs slightly, but for most applications, they're a direct fit for achieving that improved stance and handling.
