I know 12.5 bear claws on stock rims fit on a Rancher but i ordered 12.5 on rubi rims and i am starting to wonder if that it isnt going to fit so i am looking at spacers. Are the moose spacers any good...and do these really do any damage.

 

They cause a little extra stress on your f&r bearings and front shocks .. but It should be alright if you don't plan on doing any jumping, which by the sounds of your rancher you don't.

 

I had 26x12x12 vamps on Rubicon wheels on our old Rancher. With the stock muffler they wouldnt fit. I used that as a perfect opportunity to get the performance kit since the SuperTrapp muffler is only 3 inches wide.
