Top End Refresh Kit for Can-Am Maverick X3 1000
The Can-Am Maverick X3 Top End Refresh Kit is designed for 2017-2023 engines with reusable pistons, cylinders, and valves that only require replacement of common top-end wear items. It includes piston rings, valve guide seals, and the gaskets typically replaced during top-end service.
Before You Begin Your Refresh
Inspect the Top End Carefully
Inspect the pistons, cylinder walls, valve faces, and valve seats before ordering. If you find damaged pistons or worn valves, a complete or master top end rebuild kit may be the better choice for your repair.
