Can-Am Defender HD8 Bottom End Refresh Kit

The Can-Am Defender HD8 Bottom End Refresh Kit gives your 2016–2021 Defender 800 a focused lower-end service without a full rebuild. It targets sealing, bearing support, and timing accuracy so you can stop leaks, smooth rotation, and protect the crank and cams. As a result, your HD8 runs cooler, quieter, and more reliably.

This Kit Includes:

• Oil Seal Kit
• (2) Timing Chain
• Complete Gasket Kit
• Water Pump Seal
• Bearings

This Can-Am Defender HD8 Bottom End Refresh Kit tackles the most common lower-end wear points. The oil seal kit and complete gasket kit help prevent oil and coolant leaks after reassembly. Additionally, the timing chains keep crank-to-cam timing precise, which protects top-end components and preserves power. Meanwhile, fresh bearings reduce friction and noise, while the water pump seal helps maintain stable cooling under load.

Choose this refresh kit when your HD8 shows leaks, chain slack, or bearing noise but the top end still checks out. It offers more coverage than a quick fix; however, it avoids the cost of a full rebuild. Moreover, pairing this bottom-end refresh with a top-end kit creates a comprehensive service that extends engine life and improves overall performance.

All components meet or exceed OEM standards for fit and durability. Therefore, shops and experienced DIY builders can install the kit with confidence. Like every REV6 package, you’ll get nationwide shipping and our 1‑year warranty for peace of mind on the trail or at work.
