NOTE: 510G camshafts may use stock style non-adjustable pushrods instead of adjustable pushrods. If installing non-adjustable pushrods, disassemble
and assemble rocker boxes per H-D® instructions. All other S&S® gear driven cams require installing adjustable pushrods. As a time-saving measure, the
stock pushrods can be removed with bolt cutters. Be sure to head caution and warnings of these instructions.
