Good To Know
Q: Should the ring end gap be measured before installation? A: Yes, always verify the end gap within the cylinder to ensure it meets factory specifications for your specific piston.
Q: Is a break-in period required for new rings? A: Yes, a brief break-in period helps the ring seat properly against the cylinder wall for a better seal.
