Can-Am Defender HD8 Complete Top End Rebuild Kit

The Can-Am Defender HD8 Complete Top End Rebuild Kit is built for 2016–2021 Defender 800 owners needing a dependable top-end restoration. This kit replaces all major top-end components, helping restore lost compression, improve airflow, and stop leaks in one streamlined job.

This Kit Includes:

• (2) Cylinder
• Top End Gasket Kit
• (2) Piston Kit

The cylinders are precision-machined for proper fit and sealing, while the piston kits deliver renewed compression and power. The top-end gasket kit ensures leak-free operation once your rebuild is complete. This Complete Top End Kit offers everything needed for a solid upper-end refresh without the valves found in a Master kit, making it a practical choice when your existing valves are still in serviceable condition.

Ideal for high-hour engines, worn cylinders, or loss of performance, this kit provides OEM-level reliability with the durability REV6 is known for. Installation is straightforward for experienced DIY mechanics or professional shops.

All REV6 kits come with nationwide shipping and a 1-year warranty. If you’re unsure whether a Complete Top End Kit or another option fits your needs, our team can guide you to the right choice.
