Lightweight Platinum Series Pistons: Excellent for Drag Racing

Popular among professional engine builders & elite tuners, Manley Pistons use domestic high-strength 2618 alloy forgings and unique-to-Manley fixturing that allows skirt turning/ring groove machining to be performed in a single operation; this ensures the ultimate ring groove-to-skirt squareness for a better ring seal. Plus, powerful Manley cam & barrel (skirt) profiles are "easy" on cylinder walls.
