Whether you’re swapping engines in / out of your Can-am Defender, looking for replacement engine parts / components, or simply looking for the best way to maintain and extend the life of your UTV engine, here at Everything Can-Am Offorad, we’ve got the engine parts, kits, and assemblies to make any engine-related task easier. Many Can-am Defender owners use engine parts and even entire engines from the HP Commander or Maverick 1000 side-by-sides. They are the same style engines, but with just a few different parts. Maverick heads and cams are great replacement parts for the headers and cam shafts in the Defender engine. But if you do any engine work to your Defender, you will probably need to make the appropriate adjustments in the UTV’s ECU to maximize performance gains. Because the Can-am Defender is geared lower than other side-by-sides that are designed for speed and racing purposes, you probably won’t be able to get above 75 MPH… even if you swap in a more powerful engine. Even though the Defender is built for low-end grunt, however, with an upgraded head cam and proper tune, you should have an impressive torque curve that is leaps and bounds better than stock. And if you throw some full RJWC dual exhaust pipes into the mix, you’ll be able to squeeze every last bit of horsepower out of your engine. It should be noted also that the Mav motor can’t bolt directly onto the Defender’s transmission because it isn’t a transaxle like the Defender — using a different threw shaft and coupler. If you swap heads, though, you can make it work.

If you look around the internet, you’ll find plenty of OG Mavericks, Defenders, and Commanders with original engines and high hours. This goes to show that it’s all about how you maintain them. Treat your UTV engine with care, and it’ll give back ten-fold in the long run. One of the best ways to extend the life of your Can-Am Defender’s engine is to ensure that it is always properly lubricated. We here at Everything Can-Am Offroad appreciate Lucas, Rotella T6, and Amsoil as much as the next guy, but they are not formulated to run at the high temperatures and RPMs that occur in Rotax engines. This is why we recommend oiling your Can-am Defender engine with XPS. After all, why jeopardize your machine with any other oil beyond what the engine is tested with? So if you’re looking for engine oil, engine components, or complete, ready-to-install, engines for the Can-Am Defender, look no further than the UTV engine selection here at Everything Can-Am Offroad!
