POLARIS 14-17 RZR 1000 ENGINES

A RZR 1000 can keep running even while engine wear starts building in the background. Oil consumption, lower compression, smoke, reduced throttle response, or harder starts are often early signs that it may be time to rebuild before a bigger issue sidelines your side-by-side.

REV6 offers rebuild options designed around your goals and how you use your UTV. Many customers choose to send in their original engine core because it often helps keep the rebuild process moving, while refundable core options may be available when inventory allows. Every engine goes through evaluation, rebuild work, careful assembly, and final quality checks before shipment.

Every rebuilt engine includes our industry-leading 1-year no-fault warranty, with the option to upgrade to a 2-year no-fault, no-questions-asked warranty. Tracking information is provided after shipment so you can stay informed through delivery.

  • Helpful Answers Before Sending In Your RZR 1000 Engine

    What are common signs my RZR 1000 engine may need rebuilding?

    Lower compression, increased oil consumption, smoke, difficult starts, unusual engine noise, changing throttle response, or reduced performance under load can all be signs that the engine deserves inspection.

    What happens if my side-by-side still runs but performance has changed?

    Many engines continue operating long before failure happens. If power delivery feels inconsistent or operating behavior has changed, rebuilding earlier may help prevent additional internal wear.

    What should I expect during the first hours after installing a rebuilt engine?

    Early operation helps establish long-term performance. Monitor oil level regularly, avoid extended steady RPM, vary engine speed and load, and follow recommended break-in practices during initial use.

    How does REV6 support customers through the rebuild process?

    Our customer service and sales teams help answer questions, explain expectations, and provide guidance from order placement through delivery.

    What warranty comes with a rebuilt RZR 1000 engine?

    Every rebuilt engine includes REV6’s 1-year no-fault warranty. Customers who want additional long-term protection can also choose to upgrade to the available 2-year no-fault, no-questions-asked warranty.

    How do I stay informed after my order ships?

    Tracking information is provided with shipped orders so you can follow delivery progress, coordinate installation timing, and know when your rebuilt engine is approaching arrival.
