Good To Know

Q: Are these rings compatible with any year Arctic Cat 1000 Triple? A: They are designed for standard bore 81mm cylinders used in Arctic Cat 1000 Triple sleds, but always check cylinder condition and ring end gap during installation.

Q: Do I need to hone the cylinder before installing new rings? A: Yes, proper cylinder honing is recommended to ensure the rings seat correctly and achieve optimal compression.

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