Description
Polaris 500 Top End Refresh Kit for 1996–2013 Ranger and Sportsman Models
The Polaris 500 top end refresh kit fits engines with a reusable piston and cylinder. Inspect and measure both parts before deciding between a refresh and a rebuild.
This Kit Includes
- Piston Ring
- Top End Gasket Kit
Confirm the Piston and Cylinder Condition
First, inspect the piston for wear or damage. Next, measure the cylinder bore and check its sealing surface. If either part falls outside the correct specifications, choose a kit that includes the needed replacement.
When to Choose the Top End Rebuild Kit
If the piston cannot be reused, compare the Polaris Ranger and Sportsman 500 top end rebuild kit for 1996–2013 models. That package adds a moly forged piston to the top-end gasket kit.
When the Repair Requires Additional Parts
If the engine also needs valves, timing parts, complete gaskets, or a water-pump seal kit, review the Polaris Ranger and Sportsman 500 master engine refresh kit for 1996–2013 models.
Assembly and Ring Break-In
After assembly, follow the proper startup and break-in steps so the new ring can seat correctly. Review the REV6 engine break-in procedure guide before operating the engine.
REV6 backs this refresh kit with a 1-year parts warranty. If you need help checking the piston, cylinder, or fitment, contact the REV6 team.
