Look close, a lot of manufactures have bumpers that are "Notched" so you can use the factory type receiver hitch... Other than that about all you can do is search until you locate a bumper you like. Some are made from 1/4" thick material and are pretty heavy, others are 3/16" and a little lighter.
There are lots of Bumper posts on the JK forum.... or you can look at the Google "Images" for "Jeep Bumpers" and pick one out to look for.
One word of advice, if you want the bumper right away, make sure who ever you order from has it in STOCK !! Lots of the guys are waiting 6-8-10 weeks or more..
I like the looks and quality of the Hanson bumpers and tire carriers, first class but $$$$$....made in the USA. Others are OR-Fab, Olympic,High Rock, ACE,Fab Fours,JCR Off Road, GenRight, Rock Slide, Poison Spider...Just to name a few, there are lots of others...
I'm looking too, so good luck...hope this helps. "BH"
