Stop worrying about catastrophic engine failure caused by loose magnets. This 4Drive / Aftermarket premium flywheel is an engineered solution for Polaris 800cc ATV and UTV models. Unlike the original equipment which uses exposed magnets prone to epoxy failure, our "Capped" design features a high-grade steel sleeve that locks magnets in place permanently.
UPGRADED RELIABILITY: Built with high-temperature epoxy and a protective steel cap to prevent magnet detachment, shielding your stator from damage.
Key Features
✔ Capped Design: Magnets are encased in steel.
✔ High-Temp Epoxy: Superior heat resistance over OE.
✔ Direct Fit: Plug-and-play installation.
✔ Precision Balanced: Reduces engine vibration.

Questions & Answers
Is this a genuine original part?
This is a premium quality aftermarket replacement part, manufactured by 4Drive to meet or exceed original equipment (OE) standards for durability and fitment.
How do I know if it is compatible?
Check your original part number or vehicle year/model. If you have a Polaris 800cc (2012-2017) and your OEM number is 4013968, this is a guaranteed fit.
What makes the "Capped" design better?
Standard Polaris flywheels often have magnets that come unglued over time due to oil additives and heat. The capped design uses a mechanical steel sleeve to ensure magnets never contact the stator, even if the epoxy were to fail.
Note: Please verify your original part number against the references above before purchasing. Professional installation and air-gap adjustment (0.010") is recommended.
