Replacement piston assembly from NWP. These piston assemblies are an economical option for your top end rebuild. Piston assembly includes a piston, rings, piston pin and circlips. Pistons have a thin coat of molybdenum on the skirt, which helps reduce friction and wear during initial break in period. The piston rings are made from ductile cast iron, so your chances of breaking them during installation are greatly reduced. We recommend replacing your cylinder gaskets and using a piston ring clamp set to help when changing a piston. Gaskets are sold separately.

Important Note: Some chainsaw models have different piston and cylinder options. Please see the tabs below for specifications and fitment requirements before ordering.
