The Manley Platinum Series forged piston set for Chevrolet LS engines with a 3.905-inch bore, 1.115-inch compression height and -18.00 cc piston volume is constructed for durable, precise engine applications. 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 approach that combines skirt turning and ring-groove machining enhance ring seal and support long-term reliability for builders.
