I ordered the same wheels for my 96 Scram last week....just waiting for the UPS guy. Aren't the front rims 1 inch wider than stock?

 

Dune Jammer

Are you sure the wheels were not Dealer installed? Are they Grey or Polished?
Dealers will sometimes put them on floor models to help catch an eye. They just look so much better.
I know the 2000MY did not come with them (FACTORY), 4x4 or 4x2. Polaris does offer them in the Parts Catalog.

 

Dunes rims may be painted white !!!! Again, there seems to be no rhyme or reason to what parts will get put on a Scrambler. Some quads get aluminum parts, some get steel... I guess it depends on which part is on the top of the parts bin when they're assembling the quad.

When the Scrambler 500 X came out, there was a label attached to the silver painted aluminum wheels that read: CUSTOM ALUMINUM RIMS . These are the same rims that are supposed to be on the 400 2X4's.
