Summit Racing™ Pro LS Forged Pistons

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™ Forged Pro Pistons

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!
