UMI Performance 78-88 G-Body Lowering Spring Kit 1in Lowering

If you're looking to give your 1978-1988 G-Body a sportier stance and more responsive feel, this lowering spring kit from UMI Performance is a solid option. These springs are designed to lower your vehicle by about 1 inch, reducing body roll and that common “floating” sensation without making the ride too harsh. They're a great choice whether you're setting up for some Auto-x, Pro-Touring, or just want a more comfortable cruising experience with better cornering.

UMI didn't just grab any old spring; they worked with a Sprint Cup chassis engineer to develop these. The front springs are built from 5160 Chrome Silicon wire and have a linear rate of 600 lb/in, while the rears use 9254 Chrome Silicon wire with a 130 lb/in linear rate. This linear rate means the spring’s stiffness changes predictably as it compresses, giving you consistent handling. They come with a tough black powder coat finish and are made right here in the USA, so you know they're built to last and keep your car sitting right for years.

This kit fits a wide range of G-Body vehicles, including popular models like the Chevrolet Monte Carlo, Buick Regal, and Oldsmobile Cutlass Supreme, as well as many S10 and S15 trucks. Keep in mind that if you're running a very light car, you might need to trim the springs slightly to achieve the perfect 1-inch drop, but for standard SBC or LS power, they should sit right.
