The UMI rear spring spacer (3/16") provides a simple way to fine-tune rear ride height to improve stance or prevent tire rub on GM A-, G- and F-Body applications. Zinc-coated, laser-cut mild steel spacers are stackable in 1/8" or 3/16" thickness; P/N 0063 is one 3/16" spacer. OD 3-3/4" and ID 2-7/8" make fit verification easy. Normal install is on the upper perch with no cutting, welding or drilling required.
