Description
Complete Gasket and Seal Kit for Can-Am Maverick X3 1000
The Can-Am Maverick X3 Complete Gasket and Seal Kit includes the sealing components commonly replaced during a complete engine rebuild or major engine service. Instead of sourcing individual gaskets, seals, and O-rings, this kit provides the components needed to help restore proper engine sealing from top to bottom.
Replacing worn sealing components while the engine is apart helps reduce the chance of oil leaks, coolant leaks, and repeat labor after the rebuild is complete.
Before You Begin Installation
Prepare All Sealing Surfaces
Before installing new gaskets and seals, thoroughly clean every sealing surface and inspect for scratches, corrosion, or damage. Proper surface preparation helps new components seal correctly and supports long-term reliability.
