Description

The Sealed Power L2256F 40 is a forged piston designed for high-performance street, truck, marine, and racing applications. It features a 4.000 inch bore, a 1.563 inch compression height, and -6.10 cc dish volume with four valve reliefs.

The piston is constructed from VMS-75 aluminum alloy and includes a DUROSHIELD skirt coating for scuff resistance and reduced bore clearances. It utilizes 5/64 x 5/64 x 3/16 inch ring grooves and requires a press-fit pin, meaning the engine must have a press-fit rod.
