Note: This is a "Size A" piston. In high-precision engine rebuilds, these are often graded (A, B, C) to match the specific bore size of the cylinder. Always check your cylinder markings before ordering.
Fitment Details
This assembly includes the piston specifically graded as size "A." When performing a top-end rebuild, it is highly recommended to also replace the piston rings, piston pin, and circlips to ensure the longevity of the new assembly. Furthermore, verify that the cylinder bore is within the manufacturer's specifications for a "Size A" piston to ensure correct ring end-gap and piston-to-wall clearance.
