The Ross 95761 pistons are also coated with a high-phosphorus, nickel-coated skirt, which provides additional protection against scuffing and wear. This coating also helps to reduce friction, which can improve engine performance and reduce the risk of engine failure.
In addition, the pistons also have a 1.750-inch diameter pin boss, which provides additional strength and durability. The pin boss is also drilled and tapped for a 5/16-24 pin, which is a standard size for most racing applications.
