Can-Am Defender HD8 Exhaust Valve Kit | 2016–2021

The Can-Am Defender HD8 Exhaust Valve Kit gives 2016–2021 Defender 800 owners a precise fix for heat‑stressed or worn exhaust valves. If you’re chasing low compression, rough idle, or misfires tied to leaking valves, this targeted kit helps you restore sealing and protect your top end—without buying extra parts you don’t need.

This Kit Includes:

• (4) Exhaust Valve

Exhaust valves endure extreme temperatures and pressure every ride. Over time, they can burn, warp, or pit. Consequently, the engine loses compression and efficiency. By installing new, precisely machined exhaust valves, you improve sealing at the seat, stabilize combustion, and bring back smooth power delivery. In many cases, you’ll also notice cleaner plugs and fewer exhaust pops on decel.

Use this Exhaust Valve Kit when inspection shows margin loss, face erosion, or out‑of‑spec runout on the exhaust side. If your intake valves and guides still measure within spec, this kit is the efficient choice. However, if the entire valve train needs attention, consider our Complete Valve Kit or a top‑end rebuild package for a broader refresh. Either way, we can help you choose the right path for your HD8.

All components meet or exceed OEM specifications for fit and durability, so shops and experienced DIY mechanics can install with confidence. For best results, check seat concentricity, verify spring heights, and finish with a proper leak‑down test. This approach ensures your new valves seat correctly and deliver long service life.
