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 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!

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

ICON FHR Series piston and ring sets for GM LS offer premium, custom options in an "off the shelf" option for your LS-family engine. FHR (Formed Head Relief) pistons have valve reliefs that are formed in as the piston blank is pressed into the die, creating a stock, but light forging. Many of the domed models are solid which allows tailoring the dome height for a specific compression ratio. They are constructed from high-strength, forged 4032 aluminum alloy for increased durability while maintaining tighter piston-to-wall clearance for increased cylinder sealing, lower cylinder wear, and stock-like noise levels, making them ideal for street and lightly boosted applications. Completing these kits are file-fit ring sets that allow custom ring gaps for your specific application, and they are built to handle the abuse of stock street or forced induction to nitrous applications. ICON FHR Series pistons for GM LS also feature: * Mini grooves allow an overheated piston that contacts a cylinder wall to transfer heat to the wall. Friction is also reduced over a solid ringland. * Accumulator grooves provide a reservoir area for gases that pass by the top ring. Pressure is reduced between top and second ring to help stabilize flutter and maximize ring seal. * 0.030 in. offset wrist pins * Round wire locks * M42 skirt coating
