I added product listings for the new UCF Ultra High-Clearance Transfer Case Skids.  These skid plates are only 1″ deep.  They require the use of a 2″ body-lift if you want to install them without any tub interference.  They can be installed with a 1″ body lift if you clearance the tube at a couple areas on top of the transfer case.  Installing one of these skids on an ‘03-06 TJ yields as much belly-clearance gain as installing tires that are 7″ larger in diameter.
