The Manley Platinum Series forged piston set for Chevrolet LS engines with a 4.080-inch bore, 1.065-inch compression height and -20.00 cc piston volume balances strength and ring sealing for performance builds. Manley uses domestic 2618 alloy forgings, cam-and-barrel skirt profiles and tool-steel wrist pins, with moly skirt coatings on select SKUs. Exacting ring lands and a unique fixturing process that combines skirt turning and ring-groove machining support reliable ring seal and longevity.
