Description
Polaris 800 Master Top End Refresh Kit for RZR, Ranger & Sportsman Models
If your Polaris 800 engine is showing signs of valve wear, reduced compression, or aging top-end components, this Master Top End Refresh Kit provides the parts needed to restore performance and reliability. Designed for applicable Polaris 700 and 800 engines, this kit combines common top-end service components into one convenient package.
Because top-end wear develops gradually over time, replacing rings, valves, and gaskets during maintenance can help improve engine sealing and extend service life.
This Kit Includes
- Top end gasket set
- Piston rings
- (2) Intake valves
- (2) Exhaust valves
Fitment
Fits applicable Polaris 700 and 800 models from 2003–2012, including many:
- Polaris RZR 800 models
- Polaris Ranger 800 models
- Polaris Sportsman 700/800 models
Category Note: This product is commonly purchased for 2008–2010 Polaris RZR 800 and Ranger 800 rebuild projects, although fitment extends beyond those model years.
Restore Top-End Performance
Piston rings, valves, and gaskets are among the most common wear items found during top-end service. As a result, engines may experience compression loss, harder starting, reduced power, or increased oil consumption.
Replacing these components helps restore sealing efficiency while addressing many of the common wear points found in higher-hour Polaris 800 engines.
