Frequently Asked Questions

Q: Does this cylinder come with a piston kit?
A: No, this listing is for the cylinder only. However, we highly recommend pairing this with a fresh piston kit for optimal break-in and performance.

Q: Is any machining required before installation?
A: No. This is a "drop-in" ready cylinder. It comes pre-plated and honed to the correct specifications for a standard bore piston.

Expert Pro-Tip: When installing a new cylinder, always ensure your cooling system is flushed and fresh coolant is used. Many top-end failures occur not because of the cylinder, but because of old, degraded coolant failing to pull heat away from the combustion chamber properly.
