The Manley Platinum Series forged piston set for Chevrolet LS engines with a 4.005-inch bore, 1.115-inch compression height and -18.00 cc piston volume supplies a balance of strength and sealing for tuned engines. Manley builds these pistons from domestic 2618 alloy forgings and fits proven cam-and-barrel skirt profiles with tool-steel wrist pins, plus moly skirt coatings on select SKUs. Precise ring land and groove standards and unique fixturing for combined skirt turning and ring-groove machining promote improved ring seal and longevity.
