The Summit Racing Pro LS forged pistons are affordable and built to withstand the rigors of high boost and nitrous. These pistons are forged from Premium 2618 alloy - the strongest made. They have specially profiled piston skirts, which allow them to run a tight piston-to wall-clearance for maximum ring seal and minimal friction. They have many other high-tech features too! • Maximum ring-land thickness for power-adders • Dedicated forgings for the best strength-to-weight ratio • Multiple compression ratios specifically targeted for 4.8L, 5.3L, 5.7L, and 6.0L engines • Designed around Premium file fit rings with Gas-Nitride or Plasma steel tops and ductile Napier second rings • Available in versions for Gen. 3 Press-fit, Gen. 4 Floating, and Aftermarket 6.125 rods • Standard and Stroker versions available • Generous valve reliefs that work with both Cathedral port AND Rectangle port heads • Pressure-fed pin-oiling • Pressure seal groove in 2nd ring land for increased seal. • High-Speed brush deburring to remove sharp edges that cause detonation • Ultra-Modern 2.250 pin forgings clear the reluctor rings with stroker cranks • Durable Chromium Steel wristpins. • Replacement Singles Available

Summit Racing™ offers coated hypereutectic pistons to furnish you with a more affordable engine build. These internal combustion engine pistons are cast using a hypereutectic aluminum alloy—and then layered with a special "break in" coating that wears to the cylinder walls. This coating provides an extra level of protection in three ways: superior thermal and wear characteristics to increase the piston strength; scuff and seizure resistance; and improved groove wear. Whatever your piston requirement, Summit Racing™ has you covered! Order the size and options needed for your application.

Make your engine rebuild more affordable with Summit Racing™ coated forged pistons! They offer the strength of a forging at a cast piston price. They're forged from 4032 aluminum, an alloy containing silicon—which controls the thermal expansion for tighter piston-to-wall clearances. This unique alloy and design reduces piston wobble, limits noise, improves piston ring seating, and increases the overall life of skirts and pin bores. The special coating on these forged pistons adds extra protection from both skirt scuffing during cold starts or on an overheated engine. These sets are available in dozens of models/options to fit applications from 1967 and up. Summit Racing™ coated forged pistons will meet your engine demands!

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

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!

Our Summit Racing™ piston rings by Hastings are an incredible value at this price. They feature Hastings Flex-Vent oil control rings to eliminate blowby, and cast-iron second groove rings with a reverse-twist taper face for reduced friction. Sets that include cast iron barrel-face top rings are suitable for stock and mild performance applications, while the sets that include plasma-moly coated top rings are designed for high performance and bracket race applications. These piston rings are available in a variety of sizes and other options—in universal and application-specific models.

Summit Racing™ Forged Pro Pistons brings modern engine piston technology to older engine platforms at the great value. Why use an antiquated piston designed fifty years ago in your new build? A great piston starts with a great 2618 forging. Forged Pro piston forgings are stronger AND lighter. This makes more power AND takes stress off the crank, rods and block at higher rpm. It also saves money balancing a crank when heavy metal is not required. Forged Pro pistons are designed around ultra-modern Nitride Steel top ring packs and Summit GP Gas Ported variants. Less friction results in more power and less bore wear. Superior machining results in less blowby for less oil consumption and longer life is the result. Better rings are great horsepower per dollar! Most old production engines were designed to run on 87 octane in heavy vehicles. If you're building a performance engine, chances are you're running it on 91+ octane and you might as well add a little pop. Forged Pro pistons yield an extra 1/2 point of compression in most instances. This is free power from idle on up for the life of the engine! Forged Pro pistons have extra thick ring lands for moderate boost and nitrous. Special care has been taken to deburr critical areas for more strength and less chance of detonation. Special skirt profiles are designed to run at tighter clearances than other forged pistons for less piston rock. This helps them make more power, run quieter and last longer than other forged pistons. Make your build run with the best of them!
