Includes a 1.5mm x 1.5mm x 3.0mm ring set (high-grade steel gas nitrided barrel faced tops, Taper Hook Groove Napier second rings, and 3-piece soft nitrided rail flex vent oils for severe duty applications). Comes with chromoly wrist pins with wire locks. FEA designed forging, made in the USA with tight tolerances. These pistons have a minimum pin boss span of 1.060" and use a 2.250" long wrist pin.
