Frequently Asked Questions

Q: How do I know if I need a 0.040" oversize ring?

A: You should use a 0.040" oversize ring only after your cylinder has been bored and honed to 0.040" over the standard factory specification. Always measure your cylinder bore with a precision bore gauge before purchasing to ensure the correct fit.

Q: Is this ring compatible with standard-bore Raptor engines?

A: No. This ring is specifically designed for engines that have been machined to a 0.040" oversize. Installing this on a standard-bore piston will result in improper ring end gap and potential engine failure.

Q: Do I need to gap these rings before installation?

A: Yes. Even with precision-manufactured rings, you must check the ring end gap inside your specific cylinder bore to ensure it meets the manufacturer's clearance specifications for your racing application.

Q: Can I use this ring for both stock and modified Raptor builds?

A: Yes, this ring is engineered for versatility. Its design provides the necessary pressure retention for stock refreshes while maintaining the durability required for high-performance modified Raptor powerplants.
