Summit Racing™ Coated Forged Pistons

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!
