Summit Racing™ Pro LS Wrist Pins
Summit Racing™ Pro LS wrist pins are the toughest on the market—powerfully built for extreme boost and nitrous. They're specifically developed for Summit Racing™ Pro LS pistons and others that use a 2.250 in. pin length for Spiralocks to clear the reluctor ring without notching. Make no mistake, during high-contact stress and impact loading applications, you'll want the confidence that Summit Racing™ Pro LS wrist pins provide! * Part number SUM-S719 is made from H-13 tool steel, an alloy with 289,000 psi tensile strength (vs. common 9310 alloy tool steel pins at 187,000 psi) * Part number SUM-S720 adds diamond-like coating (DLC) to the H-13 tool steel for increased durability, hardness and much lower friction * The DLC wrist pins (SUM-S720) provide better lubricity for use with low-silicon 2618 alloy pistons that may have pin-bore galling issues at the extremes without DLC * H-13 tempers at 1,000 degrees F and readily accepts DLC application (at 400 F) without structural changes * Rockwell hardness: 54 HRC * Increased ductility of 30,500 ksi compared to other materials * Surface-finished to an RA of less than 1 and a concentricity of .000040 in. * 0.215 in. wall-thickness—the thickest on the market for ultimate strength * Only 135 grams * I.D. honed to remove stress-risers
