Good To Know

Q: How do I confirm this seal kit fits my ATV? A: It is listed for Polaris Sportsman 300 4x4 models from 2008 through 2010, so check your model year and drivetrain setup before ordering. Comparing your machine's serial number to the listing details is the most reliable way to confirm compatibility.
