Built to Work. Rebuilt to Last.

Your Polaris Ranger 570 deserves an engine that pulls hard and won’t quit. With REV6, you send in your engine core and we rebuild it better than new. Our technicians measure, machine, and assemble every component to tight specs, so your Ranger fires up clean, runs cool, and makes reliable power.

How the Core Program Works

• Send your core: Ship us your Ranger 570 engine core (clean and drained).
• We rebuild: Tear-down, cleaning, machining, upgraded parts, and precision assembly.
• Quality check: Double inspection and final verification before return shipping.
• Back to work: Install, break in, and get back to the job or trail with confidence.

What We Rebuild & Replace

• Crankshaft, bearings, and seals for smooth, durable rotation
• Cylinder, piston kit, and rings for strong compression and clean burnTiming chain, guides, and tensioner for steady valve timing
• Oil pump, chain, and regulator to maintain proper oil pressure
• Gasket and seal coverage across all key interfaces
• Cylinder head service (valves, guides, seats, stem seals) as required
