Can-Am Defender HD8 Top End Refresh Kit

The Can-Am Defender HD8 Top End Refresh Kit gives 2016–2021 Defender 800 owners a focused upper-end service without replacing more parts than necessary. Use it when your cylinders and valves still measure in spec, yet you want to restore compression, reduce oil consumption, and stop annoying leaks.

This Kit Includes:

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

The piston ring kits help reseal the cylinder walls, which improves compression, throttle response, and overall efficiency. In addition, the top end gasket kit provides fresh sealing surfaces so reassembly stays leak-free. Together, these components refresh the top end quickly, cleanly, and cost‑effectively.

Choose this Top End Refresh Kit for high-hour engines that show blow‑by, oil use, or minor sealing issues but don’t need new pistons, valves, or cylinders. If you discover scoring or valve leakage during teardown, consider stepping up to a Top End Rebuild or a Complete/Master Top End kit for broader coverage. Our team can help you compare options based on symptoms, hours, and budget.

All parts meet or exceed OEM specifications for fit and durability. Therefore, experienced DIY mechanics and professional shops can install this kit with confidence. Pair it with a bottom-end refresh if you also want to address bearings, seals, and timing chains for a more comprehensive service.
