Description

Bring your Can-Am Maverick 1000 X3 back to full strength with the REV6 Master Engine Refresh Kit for 2017–2023 models. This all-in-one package replaces every key wear part—valves, piston rings, bearings, gaskets, and seals—so your engine runs tight and smooth again. Each part is built to match or beat OEM specs, giving you lasting performance without guesswork.

Upgraded intake and exhaust valves help restore power and airflow. In addition, new piston rings and fresh bearings rebuild your compression and bottom-end strength. Because the kit also includes a full gasket and seal set, you can stop leaks before they start. As a result, your machine runs cleaner, cooler, and stronger for years to come.

Every component is checked by REV6 technicians before shipping. That’s why each kit fits right the first time and holds up under real-world riding. Also, we ship nationwide to keep your project moving fast and your sled ready for the next trip.

This kit comes with a 1-year warranty and an option for 2-year no-fault coverage. You can also use our financing plans or core return program for more savings. For rebuild help and simple how-to tips, check out the REV6 Blog.
