Bottom End Refresh Kit for Can-Am Maverick X3 1000
The Can-Am Maverick X3 Bottom End Refresh Kit is designed for 2017-2023 models with reusable major engine components that only require replacement of common lower-end wear items. It includes crankshaft bearings, connecting rod bearings, a cam chain, and essential sealing components to help restore dependable engine performance.
Replacing bearings, timing components, and critical gaskets during a planned engine service helps improve reliability while reducing the chance of reopening the engine later for routine wear items.
Before You Begin Your Refresh
Inspect the Lower End Carefully
Before ordering, inspect the crankshaft journals, connecting rods, and bearing surfaces for wear or damage. If these components are outside manufacturer specifications, a bottom end rebuild kit may be the better repair option.
