Frequently Asked Questions

Q: Does the ring type matter?
A: Absolutely. Wiseco ring types are not interchangeable. Always check the dome of your piston for the stamp (e.g., "C", "G", or "H") to ensure you are matching the correct ring style to your specific piston model.

Q: Is the cylinder sleeve included?
A: No, this kit includes the piston, rings, and gaskets. If your cylinder has deep scoring, you will need to purchase a cylinder sleeve or a new cylinder separately.

Expert Pro-Tip: When installing a new forged piston, ring end-gap clearance is critical. Forged pistons expand more than cast ones, so if the ring end-gap is too tight, the ring ends will butt together and shatter your piston lands. Always file-fit your rings according to the included manual to ensure they have enough room to expand safely at operating temperature.
