Can-Am Defender HD8 Engine (2016–2021)

The Can-Am Defender HD8 Engine from REV6 is built to be as good as new—or even better. Designed for all 2016–2021 Defender HD8 models, this engine includes extensive upgrades for durability, performance, and long-term reliability. Every build goes through our rigorous double inspection process to ensure your engine meets our high standards before it leaves the shop.

Included Features and Upgrades:

• Standard 1-year warranty, with optional 2-year no-fault coverage
• Upgraded forged crankshaft assembly with stronger alloy and improved heat treatment
• New cylinder assembly with 45° cross hatch for better oiling
• Upgraded forged nitride valves for higher RPM durability
• Upgraded manganese bronze valve guides to reduce wear and oil consumption
• Fully rebuilt and machined cylinder head—decked, seats cut, shimmed, and leak-down tested
• High-temperature valve stem seals to resist heat cycling
• Factory intake and exhaust camshafts
• Upgraded main crankshaft bearings with babbitt coating
• Balance shaft bearings
• Aftermarket timing chain and oil pump chain
• Factory timing guides
• Complete oil pump assembly with fixed regulator
• Aftermarket chain tensioner
• Inspected and machined engine cases tested for wear, cracks, or damage
• All seals and gaskets needed for engine assembly

Our master technicians assemble your engine, then a second master technician inspects it before shipment. This double-inspection guarantee means your engine arrives better than factory fresh. We back every build with nationwide shipping and a 1-year warranty, with the option to upgrade to our 2-year no-fault coverage for complete peace of mind.
