Polaris Ranger 800 Engine Remanufacturing Service (2011–2017)
If your 2011–2017 Ranger 800 is losing power, making internal noise, or burning oil, it’s time for a proper engine rebuild. Instead of replacing the machine, our precision remanufacturing service restores factory reliability while reinforcing critical wear areas.
This is a core-required service. Send in your original engine core or pay a refundable $1200 core charge. Once your core is inspected and approved, that charge is refunded in full. Before shipping, review our engine shipping instructions to ensure proper preparation. We provide insured nationwide shipping to keep the process straightforward.
What This Engine Rebuild Includes
- Standard 1-year no-fault warranty
- Optional 2-year no-fault warranty upgrade available
- Complete teardown, cleaning, and detailed inspection
- Cylinder head cleaned, decked, rebuilt to specification, and vacuum tested
- Valve guides inspected and replaced as required
- Valves and seats recut and refaced to ensure proper sealing
- Camshaft lobes and journals cleaned and polished
- Crankshaft inspected within OEM tolerances and rebuilt with new rods if necessary
- New high-babbitt coated main and balance shaft bearings
- Refurbished and hone-finished nikasil coated cylinders
- New moly-coated pistons and rings
- Fully inspected engine cases checked for cracks and journal wear

Additionally, we restore viable OEM components whenever possible to maintain factory engineering standards. However, high-wear parts are replaced to prevent premature failure. As a result, the finished engine delivers dependable performance under load and in demanding work applications.
Quality Control & Build Verification
After assembly, each unit goes through a structured inspection process. Clearances, sealing surfaces, and timing alignment are carefully verified. Consequently, your engine leaves our facility built for consistent operation and long service life.

Your engine rebuild includes a 1-year no-fault warranty. Furthermore, you may upgrade to 2-year coverage for added peace of mind. To review complete details, visit our Warranty Policy. If you need guidance during the process, the Help Center and FAQ page provide additional support.
