Complete Gasket Kit for Can-Am Maverick X3 1000

The Can-Am Maverick X3 Complete Gasket Kit includes the engine gaskets, sealing rings, O-rings, and related sealing components commonly replaced during a complete engine rebuild or major engine service. Replacing these components together helps restore proper sealing and supports reliable engine operation after reassembly.

Whether you’re rebuilding the engine or repairing specific internal components, installing new gaskets during reassembly helps reduce the chance of coolant leaks, oil leaks, and sealing issues later.

Before You Begin Installation

Clean Every Mating Surface

Remove all traces of old gasket material and inspect each sealing surface for scratches, corrosion, or distortion before installing new components. Proper preparation helps the new gaskets seal correctly and supports long-term engine reliability.
