Adjustable front to back for multiple belt alignment options and belt tensioning. Works with long water pump setups. Comes complete with all hardware shown. Works with Sanden 508/514 style compressors (not included).
*Will not work with tall valve covers.
**If vehicle is equipped with power steering, must use 1981 and newer factory or aftermarket P.S. brackets that bring pump closer to water pump. See installed picture for proper location/fit.
