Specially developed for use with Diamond's pistons, the H-13 Series wrist pins are an H-13 tool steel alloy—quite possibly the best all-round wrist pin material for high horsepower "power adder" engines. Designed to further reduce reciprocating weight, the H-13 Series piston pins have a Rockwell hardness around Rc54, and easily accepts a DLC (Diamond-Like Carbon) coating. Make no mistake, during high-contact stress and impact loading applications, you'll want the confidence that the H-13 Series wrist pins can provide! Order the piston wrist pins designed for your application needs.
