I really don't care your intended use for the LC, be it mall crawling, dirt roads or wheeling.
There are a few rear bumpers I really like,
@Delta VS has a really nice rear bumper, 4x4 Labs makes a great one and
@Ken in AZ can get you in touch with Avid Offroad here in AZ. They have a good looking rear bumper too.
4X4 Labs has a "kit" bumper so if you can weld or have a buddy that can weld you can save yourself some money there. With Avid Off Road's bumper, I like the side flares and the underside of their bumper, mainly the mounting bolt protection, among other things.
