UMI Performance Spring Spacer Kit

If you're looking to dial in the rear stance on your classic GM muscle car or later model F-Body, these spring spacers from UMI Performance are a straightforward solution. They offer an easy way to make small adjustments to your rear ride height without any cutting or welding, helping you achieve that perfect look or prevent tire rub when you've got a load in the back.

These spacers are laser cut from mild steel and finished with a zinc coating to resist corrosion. You get a mix of 1/8-inch and 3/16-inch thick spacers in the kit, and they can even be stacked for more precise tuning. Installation is typically on the upper spring perch, though some applications might allow for use on the lower perch. This kit is designed for fine-tuning, and UMI recommends installers determine the maximum safe adjustment for their specific setup. They fit a range of GM vehicles, including many Chevrolet Chevelle, Pontiac GTO, and Chevrolet Camaro models.

This kit includes four 1/8” spacers and two 3/16” spacers, giving you options to get your ride height just right. They're made in the USA and are a popular choice for enthusiasts looking for that subtle but important adjustment to their vehicle's profile.
