Polaris Ranger 570 Remanufactured Engine (2022-2026)

If your 2022-2026 Polaris 570 Ranger engine has developed low compression, excessive oil consumption, or bottom-end noise, we rebuild your original engine to restore strength and reliability.

You may also choose to pay a refundable $800 core charge if you need your rebuilt engine first. Once your original core qualifies, we refund the full amount. Contact us to discuss core exchange options.

Before You Buy — Please Verify Your Crankshaft and Cylinder Head Type

This crankshaft replace OEM part number 2206356. The tapered end of the crankshaft has a diameter of 25mm, just behind the threaded end for the flywheel. The cylinder head is OEM part number 3022860. The exhaust port uses a flat graphite gasket with the header pipe mounting flush against the cylinder head. Please confirm your crankshaft MAG end diameter and exhaust port. Polaris made changes to the crankshaft in 2017, but the cylinder head has mixed use starting in 2021. We recommend to confirm these parts are correct for your specific machine prior to purchase.
