Description

The Sealed Power H640DCP 40 is an engine piston set designed for durability and performance. Constructed from hypereutectic material, these pistons offer excellent strength and scuff resistance, allowing for tighter bore clearance and improved sealing to minimize blow-by. They feature sophisticated barrel profiles to optimize the oil wedge and are protected by a DUROSHIELD® skirt coating.
