Good To Know

Q: How do I confirm this ring set fits? A: Measure your piston and cylinder bore and match it to 47.50mm before ordering, since rings are bore specific.

Q: Should rings be replaced during a top end rebuild? A: New rings are typically installed with a new piston to help seal properly and restore compression.

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