Can-Am Defender HD8 Master Top End Rebuild Kit

The Can-Am Defender HD8 Master Top End Rebuild Kit delivers a complete upper-end overhaul for 2016–2021 Defender 800 engines. Use it to restore compression, refresh airflow, and stop leaks in one focused service. As a result, your HD8 comes back with reliable power and crisp throttle response.

This Kit Includes:

• (2) Cylinder
• Top End Gasket Kit
• (2) Piston Kit
• (4) Intake Valve
• (4) Exhaust Valve

This Can-Am Defender HD8 Master Top End Rebuild Kit replaces all major wear items on the top end. New cylinders and piston kits restore proper sealing and combustion efficiency. Additionally, fresh intake and exhaust valves enhance airflow and durability under high temperatures. Meanwhile, the top-end gasket kit helps prevent oil or coolant leaks after reassembly.

Choose this Master kit when your engine shows scoring, low compression, valve leakage, or oil consumption. Unlike a Complete kit, it includes valves for a full head refresh. Moreover, installing these matched components together helps everything seat correctly and run smoother for the long haul.

REV6 backs you with nationwide shipping and a 1‑year warranty. Need help comparing Master vs. Complete vs. Refresh? Our team can guide you based on symptoms, hours, and budget.
