My daughter rides a 2000 trailblazer 250 and she broke the rear swing arm the previous owner must have broke it also as it was welded looking on ebay I see the newer one's are more beefier does any body know will a swing arm off of a 2005 fit a 2000 thanks

 

I have a swing arm from a 92 trail boss in good shape dont know if it help you or not. Where you located? you can have it free just pay for shipping .

 

Ther must be something special on the 2000 models not many will interchange.Check iy out here. http://parts.polarisind.com/Assemblies.asp

 

I was under the impression that any concentic drive will work 2 or 4wd.

 

I was too until I cross referenced this one

 

Looks like all 2wd are open tubing and all 4wd are partially or totally boxed in or reinforced tubing. Also some have a different shock mount. The non reservoir shock mounting point is closer to the pivot point (mounted on top of the tube) and the reservoir (fox) shock is back towards the axle about one inch (mounted on the corner of the tube). The microfisch doesnt show this but is is a fact. My '99 was on top with the non reservoir and I coppied a lower mount off a buddies '03 and made my own brackets to mount a reservoir style correctly.
