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”
