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

It has long been recognized that thin rings make more horsepower due to a reduction in friction and better ring sealing, and many piston manufacturers offer standard, thinner ring grooves for this reason. Unfortunately, the choices for thinner ring packages are expensive and often made of inferior materials. Total Seal TFX piston rings utilize proprietary ring manufacturing processes, high-quality 440B stainless and 9000 Series steel, and Total Seal's proprietary C56 face coating. The result--a high horsepower and torque per dollar ratio, with decreased wear and oil consumption (when coupled with a properly honed cylinder bore). Total Seal TFX ring sets come in two ring thickness packages covering most domestic and import applications. Select the proper bore size and groove dimension needed for your application. Total Seal TFX ring features: * Well suited for normally aspirated, boosted, or nitrous applications * Available in all popular bore sizes * 440B stainless steel top ring with proprietary C56 face coating * Steel, Napier profile 2nd ring * Standard tension oil control rings
