Is your Polaris ATV having ignition or starting issues? This replacement flywheel rotor might be the fix. It's a direct fit for a bunch of older Polaris models, including the BigBoss 500, Magnum 500, Ranger 500, Scrambler 500, Sportsman 400/500, and Worker 500 from the late 90s to early 2000s (check the exact years in the description). It matches OEM numbers 3085558 and 3086819. Made from durable materials, it's built to handle vibration and heat, providing consistent spark for reliable starts and smooth running. Precision-engineered to align correctly with your stator. If your old flywheel is damaged or demagnetized, swapping this in can save you a headache. Just make sure your model and year match before ordering.
