Diamond Pistons Marine Series Pistons
Diamond Pistons Marine Series pistons are ideal for your high-demand boats. These forged aluminum pistons are significantly stronger than the factory pistons allowing your engine to handle that extra horsepower, high-rpm operation and long hours on the water.
Diamond Pistons Marine Series pistons feature:
* 3D milling on piston crowns for "ready to install" finish
* Moly skirt coating for friction-loss and skirt-wear protection
* Oversized valve pockets for "larger than stock" valve sizes
* Forged 2618 or 4032 aluminum alloy (where specified)
* Premium 8620 or H-13 steel wrist pins (where specified)
