A pair of clamps with bolts and nuts for attachment. If you have an original spring or one of the authentic U.S. made springs, these are the correct clamps. To verify, these clamps will fit a spring that is roughly 1-7/32" thick where they mount. Some aftermarket springs had the hole for the spring clamp in the wrong leaf and require a taller spring clamp. We offer part number A-5330-X for those applications. The A-5330-X fits springs that are roughly 1-29/64" thick where they mount. U.S.A.
