Polaris Ranger 1000 SOHC Engine Rebuild for 2020–2023 Models

If your Ranger 1000 SOHC engine has started losing power, burning oil, or making bottom-end noise, this rebuild service brings it back the right way. Instead of patching worn components, this process restores the entire engine and reinforces key wear points. As a result, your machine handles load better and runs consistently under demanding conditions.

What Your Engine Rebuild Includes

• Standard No-Fault 1-year warranty with optional 2-year no-fault upgrade
• OEM components restored and reused whenever possible

• Manganese bronze exhaust valve guide upgrade for improved durability and high RPM performance
• Intake valve guides inspected and replaced as needed
• Valves and seats recut and verified with vacuum testing for proper sealing
• Camshaft lobes and journals cleaned and polished, replaced when required

Bottom End & Rotating Assembly

Dual Technician Quality Control

First, a master technician completes the rebuild and verifies all measurements and tolerances. Then, a second technician performs a full inspection before shipment. Because every engine passes through two stages of inspection, the final build meets strict quality standards.
