Our OE quality shackle sets are made from precision tooling, exactly like originals and exceed GM material specs. Manufactured by QS-9000 and ISO/TS16-944 certified OE suppliers. Plates are precision stamped from high grade medium carbon steel and zinc plated. Special shackle bolts are accurately shouldered, also of high grade medium carbon steel, then "thru hardened" to the same Rockwell hardness as original. Competitors use a lower grade mild steel, with poor quality stamping tooling, and the bolts as lab tested had "zero" hardness!
