This is why I decided to go with the Rockhard aluminum front bumper & there steel rear bumper & racks to help offset the weight of the 11k winch & front bumper. Works great no sag whatsoever! Didn't want to deal with spacers, coils etc on my stock Rubicon.
Real happy with the rear bumper set up 1st class all the way. Just a little unhappy with the front, looks great, functional but I ended up installing some black HMUW ? plastic to fill in the area between where there bumper ends (in front of grille) to cover up the exposed frame rails. They really ought to make there front bumpers wider at this point to fully cover all this exposed area's. Its just a cosmetic thing though! Anyway just my 2 cents!
