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.

Diamond Competition Series forged aluminum pistons are an excellent choice for pretty much any 5.0L Coyote application from 500 hp all the way up to 1500 hp. They include some very nice extras such as coated skirts, 3-D milled pockets, forced pin oiling and a very nice Total Seal AP steel ring set. Features explained: * Total Seal AP Steel Ring Set: The piston ring set included with this set of pistons is the finest shelf stocking piston ring set available. This ring set features AP Steel top rings with the C33 face coating, ductile iron Napier cut 2nd rings and a 3-piece oil ring set. The AP Steel top rings are excellent for power adder applications and have better thermal transfer and sealing properties compared to old school chrome rings. The ductile iron Napier 2nd rings offer additional oil control, which is always a bonus in high cylinder pressure applications. * Moly Skirt Coating: Helps reduce friction and protect the skirts during warmup and cold starts. This is a standard feature. Normally it will come with the Diamond logo printed. Sometimes it will come sprayed on. The only difference is the aesthetics, as both the screen print and spray on coating serve the same purpose. * Forced Pin Oiling: This is a very common add-on to many shelf stocking pistons. Forced pin oiling uses 1 or 2 cross-drilled holes on each end of the pin bore, forcing oil from the back of the oil ring groove into the pin bore. This feeds additional oil to the pin bore to prevent galling. A simple but effective machining process.
