Master Top End Refresh Kit for Can-Am Maverick X3 1000

The Can-Am Maverick X3 Master Top End Refresh Kit is designed for 2017-2023 engines with reusable pistons and reusable lower-end components that need new piston rings, intake valves, exhaust valves, and top-end sealing components. It’s an excellent choice when you’re refreshing the cylinder heads and restoring compression without replacing the piston assemblies.

Before You Begin Your Refresh

Inspect Pistons and Cylinders

Before ordering, inspect the piston ring lands, piston skirts, cylinder walls, and valve seats. If the pistons or cylinders require replacement, a Master Top End Rebuild Kit may be the better repair option.
