Product was as advertised. Heavy duty replacement, has all the factory Rubicon nuts welded in place, much stronger than stock.

I have planned to swap my crossmember for some time as it was slowly becoming very dented up from many offroad trips. The factory crossmember is very thin metal and you really see the difference with it next to the Rockhard piece. The installation was extremely easy and fitment was perfect. I highly recommend this crossmember to anyone looking for a replacement.
