This is a rock solid piece. It bolted perfectly on my '15 Sahara Unlimited. It is much more open than the stock from underneath, so tightening the nuts and bolts and doing the wiring is super easy.I installed everything with no directions because I didn't think there were any. I did find them when I was breaking down the boxes. The bumper is secured in the box with spray foam that sticks to the box. The center piece of foam was covering the directions taped to the top of the box, so tear that foam piece off to find the directions.A couple of notes when installing:1. Put the bolts for the bull bar and the fourth bolts to hold the bumper in, and then remove them, before installing the parts. I didn't do that at first. They didn't go in as easily as I expected, and I thought I was cross-threading them. It seems that some of the coating material gets on the threads making them a little tight. Putting the bolts in and removing them clears the gunk out, and they go in easily during the install so you aren't afraid that you are cross-threading them.2. Maybe the directions address this, but I didn't have them. You have to use a 10 mm box wrench to put in the lower bolt on the bull bar. A ratchet won't fit in the space-at least mine didn't.3. My state requires a front license plate. Since I had the winch, I have the piece that bolts onto the bumper over the opening for the cable. I was able to loosen that, slide the plate underneath it, and tighten it down to secure the plate. If you just have the bumper, without the winch, there are holes there that you could attach the plate. The holes on my plate didn't match up with them, so I would have had to drill new holes in the plate. The holes on the bumper are big, so I would drill a similar size hole and use that size nut and bolt to secure it.Now the one deficiency. There is only about a 9" wire on each of the four lights. Since they have to be spliced into the existing wiring, that's not long enough to be able to remove the bumper without undoing the splice and taking off the tape, etc. each time. The aftermarket LED headlights and fog lights that I had on before came with a quick connect to attach to the existing foglight wiring.I soldered about 12" of wire to each. That gives enough, I think, to be able to remove the bumper without disconnecting all the wiring. Of course if you need to move the bumper out of the way after removing it, that won't help. It would be nice if the bumper came with some kind of quick connect to address this.Overall, I'm very happy with this. I plan on 3D designing and printing housings to hold the LED foglights with halo lights that I had to remove. The bumper comes with the brackets to add a light bar. I plan on using those to reattach those foglights. If I get that done, I'll add the link to the housing files, and pictures of the final look, in case anyone wants to do the same.
