Okay! You had to ask...!
I feel that the tire is mounted about 4” higher than it should be. It seems to be made to accommodate 38” tires. I think it should have been made to accommodate 35” tires and you would have to modify it to fit larger, not the other way around. The brackets were very nice 3/16" and zinc plated, but they had one minor issue. Although BPI did supply the nut rail inserts for the frame, they were not correct. This is going to be a little difficult to explain and I wish I would have taken some pictures of these. The nut plate inserts they sent were zinc plated and well made, but they only allowed enough nuts for the bumper mounting, three on the passenger side (one for the exhaust hanger) and two on the drivers side. I had purchased two new nut rails from the dealer prior to ordering the bumper so when I put a bumper on, I would be setup for the gas tank skid. The factory ones have an extra nut that hangs out over the frame rail edge. The mounting brackets didn't leave enough room for this nut and you have to either grind the brackets at the bottom of the horizontal mounting plate or cut the extra nut off. I choose to cut the nut off since you would be able to reach it from underneath if it is ever needed for anything. Also, with this type of mounting bracket, you have to tighten it down before installing the bumper. I had to take the bumper off three or four times to adjust these so the bumper would be in the center of the Jeep. I do not see anyway around this though and you will just have to measure it closely or take the bumper on and off until you get it. I would prefer the latch to be like the factory tailgate latch. This would allow "one hand operation". This style of latch works well and it can be done one handed, but you have to fumble with it. I am also not very happy with the long swing arm either, it really puts a lot of weight on the passengers side when it is open and you have to have 4ft of clearance behind you to open the tailgate. Which means you have to park it near the front of the garage to get it open. The latch pin on the pivot side locks/holds the swing arm open, but they have it latch at the close position too. This means you have to unlock the latch on the drivers side and then go pull on the pin on the passengers side to swing the arm open. This is a nice safety feature, but a big pain in the butt. If it were to slip from your hand or have some kid swing on it, it might damage the bumper at the pivot or worse yet miss the stop hole and slam the side of the XJ. The side plates to replace the bumper caps are kind of a pain to put on because you have to remove the trim on the inside to get the nuts on. It is a real pain on the drivers side because of the gas tank fill tube runs through there and you have to reach way in there blind. If you were to drop a nut, it would be gone for good.
I will post some pictures once imagestation comes back up.
