Description
Complete Top End Kit for the 2004-2012 Polaris Sportsman 800
This package covers a more involved top-end rebuild than a piston-only or valve-only repair. It brings the supplied parts together for your 2004-2012 Polaris Sportsman 800.
As a result, you can address several areas of the top end with one parts package. The kit also keeps the repair scope clear by listing every included component below.
This Kit Includes
- Upgraded piston kit
- Complete top end gasket kit
- (2) Intake valves
- (2) Exhaust valves
Get Ready for Assembly
Before installation, clean the sealing surfaces and inspect the cylinder and head. Also, follow the correct piston direction and ring placement for this engine.
For step-by-step setup help, review the REV6 piston and ring installation guide. It explains several checks to make before the piston enters the cylinder.
Need the Valves Without the Piston Kit?
If your repair only requires intake and exhaust valves, compare the Polaris Sportsman 800 Valve Kit. That smaller package does not include the piston kit or complete top end gasket kit listed here.
Fitment
Fits Polaris Sportsman 800 models from 2004 through 2012.
Warranty and REV6 Support
In addition, REV6 backs this Complete Top End Rebuild Kit with a 1-year parts warranty. Review the coverage in the REV6 warranty policy.
Finally, order your kit with nationwide shipping from our Utah parts warehouse. If you have fitment or product questions, contact the REV6 team.
