Description
Constructed from hypereutectic material, these pistons are made with exclusive FM425 material for excellent strength and scuff resistance. This allows for a tighter bore and improved sealing, which reduces blow-by. The pistons are manufactured with state-of-the-art processes and exacting tolerances, meeting or exceeding OEM specifications.
