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

Summit Racing™ Pro GPX Gas Ported Piston Rings

You may have heard of gas ported pistons in high-end racing engines. Summit Racing™ Pro GPX gas ported rings add this performance to ANY non-gas ported (or even gas-ported) piston. They are also a great way to juice up cast and hypereutectic pistons for little extra money. How do they work? With a series of perfectly oriented slots on the top side of the top piston compression ring, the combustion pressure reaches the inside the ring groove and fully activates the ring sooner and longer for better seal. This not only makes more horsepower; it dramatically reduces blow-by and reduces or even eliminates the need for a catch can. Other benefits? Because the rings are always rotating and directly exposed to the detergents in the oil, these ports stay clean without carbon buildup that fouls out gas ported pistons over time for longer term performance. Since the rings are only activated at high pressures and no part of the cylinder sees the load repeatedly, the engine will last a long time. Nearly all our Summit™ GPX gas ported rings use top-tier nitride steel top rings, ductile seconds, and premium quality stainless oil rings. Better yet, we have them in nearly every popular bore and thickness for virtually any brand or configuration on the market. If you want to pick up power and performance, Summit Racing™ Pro GPX gas ported piston rings are the new standard at a great value!
