So the 03-06 TJs' have a slightly lower skid plate and the mounts for the transfer case put it lower as well. I think this was to make room for the rubicon air lockers and larger transfer case. At first I was bummed to hear that my jeep had a worse break over angle all so those rubis could have all the fun. Then I thought, if the transfer case is 2 inches or so lower, wouldn't that mean you could put a 2 inch lift without having to worry about an sye? Just a thought..
