UMI Performance Spring Spacer Kit - 90064Find parts that fit my vehicle

UMI's rear spring spacers may be just the ticket to achieve that perfect stance or prevent tire rub. UMI's zinc coated, laser cut mild steel spacers are available in 1/8" and 3/16" thickness and can be safely stacked. They provide an easy way to fine tune the rear ride height of your GM A, G and F-Body. No cutting, welding or drilling required. We recommend these for fine-tuning only, and maximum adjustment amount is the responsibility of the installer. Normal installation position is on the upper perch although lower perches may have adequate height (F-Body lower perch only). Kit includes four 1/8" and two 3/16" spacers. 100% manufactured, tested and raced out of Philipsburg, PA - USA.

Suspension components are key to making sure your car is riding smoothly on or off the road. With upgraded suspension components, you can unlock the full potential of your vehicles performance.

Lowering springs are a cost effective way of lowering your vehicle. Lowering springs are designed to maintain most of your car factory suspension travel while gaining a 15% increase in spring rate. If you are looking to maintain or improve ride quality while also lowering your car, we recommend coilovers first, but if your are on a budget, you can't go wrong with a set of lowering springs.
