Exhaust Valve Kit for Can-Am Maverick X3 1000

The Can-Am Maverick X3 Exhaust Valve Kit includes six OEM-spec replacement exhaust valves for 2017-2023 models. Whether you’re rebuilding the cylinder heads or replacing damaged valves, these precision-machined valves are designed to provide proper fit, sealing, and long-term durability.

Exhaust valves operate under extremely high temperatures. Replacing worn or damaged valves during a cylinder head rebuild helps restore compression, improve combustion efficiency, and support reliable engine performance.

Before Installing New Exhaust Valves

Before installation, inspect the valve seats, guides, springs, retainers, and keepers for wear or damage. For the best results, verify valve seat contact and replace valve guide seals while the cylinder heads are disassembled.
