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

JE Pistons sport compact pistons are specifically engineered for extreme applications, up to and including professional competition. In this environment, the higher compression ratios, highest boost, or heavy nitrous usage necessitate the higher tensile strength 2618 aluminum alloy. Their dome/dish requires no deburring or preparation and features smooth-flowing radii for excellent flame travel. A pin fitting, wire locks, and rings are included.
