I'm running THESE Zone offroad bump stop extensions in the 2" version on my WK with an OME MD lift and 285/70/17 BFG AT's....These have worked perfectly in preventing the fender lip from slicing up my tires. I did experience some very minor rubbing (didn't even leave a mark on the tire) at the forward most fender lip near the rear door on my last excursion, now that I folded that over last night I should be 100% rub free
