Good To Know

Q: How do I identify if I need .040 over rings? A: Your cylinder must be bored and the piston must be marked as a .040 over-bore size to match these rings.

Q: Do these rings require a break-in period? A: Yes, follow standard engine break-in procedures to ensure the rings seat correctly against the cylinder wall.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
