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 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!
