Fitment FAQ

Will this part fit my specific model and year?

This flywheel is listed for selected:

Polaris Big Boss 500 6x6 International — 1999–2002
Polaris LUH 6x6 PPS — 2002
Polaris Magnum 500 — 1999–2002

Because Polaris used different flywheel revisions and serial-number splits, confirm the original OEM number before ordering.

Do I need to match the OEM part number?

Yes. Matching the original flywheel number is strongly recommended.

Compatible replacement references include:

3085558
3086819
3086983
3087166

Also compare the ring gear, crankshaft taper, keyway, magnet layout, and overall flywheel design.

What models or situations does this part not fit?

Do not assume this flywheel fits:

Every Polaris 500cc ATV
Every Magnum 500 model without checking the original part
Flywheels with different OEM numbers
Different crankshaft tapers
Different keyway locations
Different ring-gear designs
Different internal magnet configurations

Some Polaris applications used multiple flywheel designs within the same model year.

What should I check before ordering?

Confirm:

Exact Polaris model
Model year
Original flywheel OEM number
3085558 / 3086819 / 3086983 / 3087166 where applicable
Ring gear configuration
Crankshaft taper
Center bore
Keyway position
Internal magnet layout
Overall flywheel shape

For 2002 applications, also check the vehicle serial range if the OEM parts catalog lists an early/late flywheel split.
