Polaris RZR, Ranger & Sportsman 700/800 Master Top End Refresh Kit

The Polaris RZR, Ranger & Sportsman 700/800 Master Top End Refresh Kit replaces many of the wear components found in the upper end of your engine without replacing the cylinder or piston. It includes new piston rings, intake valves, exhaust valves, and a top-end gasket set for select Polaris 700 and 800 models built from 2003-2012.

If your cylinder measures within specification and your piston can be reused, refreshing the rings, valves, and gaskets while the engine is apart helps restore compression and valve sealing without the expense of a complete top-end rebuild.

What This Kit Includes

• Top End Gasket Set
• Piston Rings
• (2) Intake Valves
• (2) Exhaust Valves

When Is This the Right Kit?

Choose this kit when inspection confirms the cylinder and piston remain in good condition, but the piston rings have worn, the valves no longer seal properly, or the upper-end gaskets need replacement. Addressing these wear items during one teardown helps reduce labor and keeps reusable engine components in service.

• Reuses a serviceable cylinder and piston.
• Includes new intake and exhaust valves.
• Replaces worn piston rings.
• Complete top-end gasket set included.

Keep Reusable Components in Service

Replacing piston rings, valves, and gaskets before they cause compression loss or oil consumption can add years of service to a healthy engine. A refresh kit lets you restore the top end while keeping reusable hard parts in operation, saving both time and rebuild costs.
