Yea.... I definately would not put 27's on a Rancher. That would be a good way to goof up a perfectly good Rancher. I just put 25" Bighorn 2's on my wife's Rancher AT and they are incredible! We do a lot of trail riding over various terrians, and the Bighorns are fabulous. The 25's add about 1.5 inches of clearance to the Rancher. If you go higher than that, you'll start negatively affecting your handling, steering, center-of-gravity, etc. I strongly recommend the BH2's based on personal experience!
