Warranty Coverage

Every REV6 engine comes with a 1-Year Warranty included. Upgrade to our industry-leading 2-Year No-Fault Warranty for even more peace of mind—if something happens, we’ve got you covered. Few in the industry can match the level of warranty protection REV6 delivers.

Our Rebuild Process

Each engine is assembled by one master technician, then inspected by another to guarantee accuracy. With more than 50 years of combined powersports and utility vehicle expertise, our team ensures your engine is ready for the toughest jobs.

Build Core Engine – What to Expect

This is a Build Core Engine, not an out-of-the-box ready-to-install unit. A solid, rebuildable core is required before shipping. During the remanufacturing process, your engine is completely torn down, cleaned, machined, and rebuilt using premium new and refurbished components. If you’re unsure about core requirements, visit our Help Center or reach out to our team for guidance.
