Product details
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). 100% manufactured, tested and raced out of Philipsburg, PA – USA. P/N 0063 is for one 3/16” spacer. Note: Spacers may work on other vehicle models. Please use the measurements to verify fitment. OD= 3-3/4” ID= 2-7/8” 90063 - Spring Spacer 3/16"
