Specs At A Glance

Good To Know

Q: How do I know this ring set fits my piston? A: Match the Wiseco part number 3189TD and the 81.00mm bore to the piston you are running. Always verify against your engine's serial number before ordering.

Q: Can I install new rings without replacing the piston? A: Yes, if the piston and cylinder are within spec, though ring end gap should be checked on assembly. Worn or scored bores may need more than rings alone.

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