Specs At A Glance

Good To Know

Q: How do I know if this chain fits my Polaris? A: Verify your model year and that your original chain is a 520x78 O-Ring type. Measure the old chain length to confirm 78 links.

Q: What maintenance does an O-Ring chain require? A: Apply chain lube regularly and keep the chain clean. The O-rings keep grease inside, so avoid high-pressure washing directly on the seals.

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