NWP Piston & Cylinder Assembly (52mm) for Stihl 046, MS460 Chainsaws (Replaces 1128 020 1221)

Replacement cylinder assembly from NWP. These cylinder assemblies are an economical option for your top end rebuild. Cylinder assembly includes a piston, rings, piston pin, circlips and cylinder. Cylinder bore is NiSi coated for long life. These pistons have a thin coat of molybdenum, which helps reduce friction and wear during the initial break in period. Piston rings are made from ductile cast iron, so your chances of breaking them during installation are greatly reduced. We recommend using a piston ring clamp set when changing your cylinder.
