Polaris Trail Boss 250 Parts Guide: Repair by Job

Frequently asked questions

Which Trail Boss 250 years can I compare when looking for a part?

You can compare Polaris Trail Boss 250 parts pages for model years 1985 to 1999, but that range does not mean every part swaps across every year. The Trail Boss 250, Trail Boss 250 2x4 and Trail Boss 250 4x4 have separate parts pages. Check fitment for your exact year, make and model before you order.

How do I identify whether my ATV is listed as Trail Boss 250, Trail Boss 250 2x4, or Trail Boss 250 4x4 before ordering?

Confirm the model designation on the quad or its paperwork, then check whether the front wheels are driven. A 4x4 has a driven front end, while a 2x4 does not. Do not choose from the Trail Boss name or body decals alone. Once identified, use the matching Trail Boss 250, Trail Boss 250 2x4 or Trail Boss 250 4x4 parts page.

When should I look for a used OEM Trail Boss 250 part versus a new replacement part?

Look at a used OEM part when you need an original hard part, such as an engine case, transmission part or other assembly that may be difficult to replace new. A new replacement makes more sense for wear and service parts such as bearings, pistons and rings. Buy brake pads and tires new. For any used OEM part from the Trail Boss 250 teardown, read its part note before ordering.
