One consideration to make is if you do get into a bender with the stock bumper, you're less likely to bend up the frame. Stock bumper tend to crumple and bend vs aftermarket tend to transmit force back to the frame. This is good if you want to go bashing at low speeds and highway doesn't matter...
Are there any inexpensive LCA options that get upgrade the LBJ to something that isn't essentially a maintenance item? Not sure I want to change them out every time I change the rad fluid.
