Can-Am Defender HD8 Top End Rebuild Kit | 2016–2021

The Can-Am Defender HD8 Top End Rebuild Kit is built for 2016–2021 Defender 800 engines that need an upper-end overhaul without replacing more parts than necessary. It’s the perfect choice when your cylinders remain in good condition, but worn pistons and gaskets are reducing compression and performance. As a result, this kit helps you regain power and reliability without the extra cost of unnecessary components.

This Kit Includes:

• Top End Gasket Kit
• (2) Piston Kit

This kit directly targets the most common wear points in the top end. The piston kits restore a proper seal against the cylinder walls, which improves compression and smooths power delivery. In addition, the top end gasket kit replaces critical seals to prevent oil or coolant leaks after installation. Together, these components bring your engine back to dependable performance.

Choose the Top End Rebuild Kit when you want to refresh performance and reliability without investing in new valves or cylinders. However, for engines showing valve wear or damage, a Complete or Master Top End Kit may be a better fit. Therefore, our team can help you decide which kit matches your needs and budget.

Like all REV6 kits, this one ships nationwide and comes backed by a 1-year warranty. Because we use OEM-quality components, the kit is ready for installation by experienced DIY mechanics or professional shops, ensuring long-term dependability.
