The Manley Platinum Series forged piston set for Chevrolet LS applications is built from domestic 2618 alloy forgings and sized for a 4.000 in stroke with a 4.030 in bore and flat-top crowns (-4cc). These pistons combine proven cam-and-barrel skirt profiles and exacting ring lands and grooves to improve ring seal. Tool-steel wrist pins and moly skirt coatings on select part numbers support durability for high-build engine assemblies.
