Warranty Coverage

Every REV6 engine comes backed by a 1-Year Warranty, so you can run with confidence right out of the gate. If you want the ultimate peace of mind, choose our Platinum 2-Year No-Fault Warranty. This upgrade gives you the best protection in the industry, because we believe in standing behind our work. Learn more in our warranty policy.

Rebuilt the Right Way

We hand-assemble every engine with care. One master technician builds it, and another verifies the work for accuracy. Because of this process, and with over 50 years of combined powersports knowledge, the REV6 team consistently delivers engines that outperform stock designs.

Build Core Engine – What to Expect

This is a Build Core Engine, not a drop-in replacement. Therefore, a rebuildable core is required. We completely strip, machine, and rebuild your core using premium new and refurbished parts, ensuring it runs better than OEM.

If you’re not sure about core requirements, check our Help Center or contact us before you order.
