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

Trend Performance is the industries elite manufacture of automotive wrist pins and offer their TP1 Series wrist pins that are machined from TP1 tool steel for maximum strength. Originally developed to replace the C350 in Pro Stock, the TP1's material is easier to machine and finish—a property which helps achieve better and more consistent surface finishes. Coatings also work better on the TP1 Series then on C350. The TP1 wrist pins are not only exceedingly hard and extremely tough, but also have the lowest coefficient of friction. That makes them a must-have for any high rpm application—and is why the TP1 pins are the top choice of many Pro Stock engine builders. Trend offers the TP1 Series wrist pins in a variety of sizes to suit your needs.

Piston wrist pins link the piston head to the connecting rod, allowing the rod to pivot as the piston moves and transmit power. They should be strong enough to withstand the pressure of combustion. JE Pistons offers Trend H13 wrist pins for your build. Made from premium H-13 steel, it is probably the best all-round material for most applications, and the perfect upgrade for your high-rpm, forced induction, or nitrous motor. These H13 piston pins have a Rockwell hardness around Rc54 and are available in numerous diameters, lengths, and wall thicknesses in chamfered or straight styles, with or without tapered walls or DLC (Diamond-Like Carbon) coating. Select the H13 pins needed for your pistons.

Mahle Performance piston rings evolved from their pioneering use of piston ring simulation and computer development tools to develop rings that provide "free" horsepower by successfully minimizing friction. A large selection of coordinated piston ring sets is available in a variety of sizes, designs, materials, and coatings designed to exceed your high performance requirements. The difference is evident on the dyno and on the track. Features and benefits of Mahle Performance piston rings: * 1mm and 2mm steel top rings with patented HV385 supersonic thermal-spray process applied for superior bonding, increased durability, and increased scuff resistance * 1.5mm and 1/16 in. positive-twist, ductile iron, barrel-faced, plasma-moly inlaid top rings * Sport compact ring sets ranging from 81-100mm with steel-nitrided top rings * Traditional, reverse-twist, taper-faced (RBT) cast iron second rings * Tapered Hook Groove (THG) second rings that offer superior oil control when compared to traditional RBT rings * 3-piece style oil control rings in both standard and low tension * Standard-tension expanders are sold separately for select low-tension rings where increased oil control is necessary * CP-20 design oil rings that are easier to install; chemically polished for better oil drain-back with a 20 degree ear angle to ensure side seal around the ring
