Master Engine Refresh Kit for Can-Am Maverick X3 1000

The Can-Am Maverick X3 Master Engine Refresh Kit is designed for 2017-2023 engines with reusable major components. Instead of replacing pistons, connecting rods, cylinders, or the crankshaft, this kit focuses on the wear items that commonly need attention during an engine refresh.

Replace the piston rings, intake and exhaust valves, bearings, timing components, gaskets, seals, and O-rings while the engine is apart. As a result, you can restore engine sealing, valve train performance, and bearing reliability without replacing serviceable hard parts.

Before You Begin Your Refresh

Before ordering, inspect the cylinders, pistons, connecting rods, and crankshaft to confirm they remain within manufacturer specifications. If these components require replacement, a complete engine rebuild kit may be the better option.
