UMI Performance Spring Spacer 1/8in

What you get here is one UMI Performance 1/8-inch rear spring spacer, made from zinc-coated, laser-cut mild steel. This spacer is designed to help you achieve that perfect stance or prevent tire rub by making small adjustments to your rear ride height. It’s a straightforward way to fine-tune your vehicle's setup, especially for GM A, G, and F-Body models, and requires no cutting, welding, or drilling for installation.

These spacers are intended for fine-tuning, and the installer is responsible for determining the maximum adjustment. While they typically install on the upper perch, some F-Body lower perches might also work. UMI Performance manufactures and tests these parts in Philipsburg, PA, ensuring they are made in the USA. The outer diameter is 3-3/4 inches and the inner diameter is 2-7/8 inches, and they can be safely stacked with other spacers if more adjustment is needed.
