Specs At A Glance

Good To Know

Q: How do I know these rings match my cylinder? A: Confirm the bore size and piston diameter for your machine before ordering, since ring size must match the original specification. Q: Should ring end gap be checked at installation? A: Yes, end gap should be measured and adjusted to the engine maker's specification during assembly.

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