One of the things that sold us on the M.O.R.E. rear bumper was how much thought the company put into the parts that you don't see, as well as those that you do. In a Unitbody vehicle, there is no thick-gauge steel frame to attach to, so multiple bolts that run down the Unitbody are needed. These brackets bolt to the body using 14 bolts and the bumper then bolts to these brackets with ten 1/2-inch bolts. We actually gained just over an inch of ground clearance over the stock bumper/trailer hitch setup we were running.
