Can-Am Defender HD8 Complete Valve Kit

The Can-Am Defender HD8 Complete Valve Kit delivers the essential top-end valve components for 2016–2021 Defender 800 engines. Use it to restore airflow, sealing, and reliability when your valve train shows wear. As a result, you can improve throttle response, reduce misfires, and cut oil consumption tied to tired valve guides or stems.

This Kit Includes:

• (4) Intake Valve
• (4) Exhaust Valve
• (8) Valve Guide Seal

The intake valves meter the air‑fuel mix into the chamber, while the exhaust valves withstand extreme heat as gases exit. Additionally, the valve guide seals help control oil at the guides, which prevents smoking and keeps the combustion chamber clean. Together, these parts refresh the valve train and support stronger, more consistent compression.

Choose this Complete Valve Kit when compression loss, oil fouling, or rough idle point to valve or seal wear. If your cylinders and pistons remain in spec, this kit is a precise, budget‑friendly fix. However, when you also see ring or cylinder damage, consider pairing it with a top‑end rebuild kit for a more comprehensive solution.

All components meet or exceed OEM standards for fit and durability. Therefore, professional shops and experienced DIY mechanics can install the kit with confidence. Moreover, replacing valves and seals at the same time helps the parts seat correctly and promotes long service life.
