The Manley Platinum Series piston set for Small Block Chevrolet LS applications features forged 2618 alloy pistons with a 4.130" bore and -11cc dish top, built for strength and consistent operation. Manley uses cam-and-barrel skirt profiles, tool-steel wrist pins and moly skirt coatings on select SKUs, while precise ring lands and single-operation fixturing help ensure square ring grooves and reliable ring seal.
