I have a UCF tummy tuck skid for oil pan through to the transfer case.
It's tough and has done a great job.
But if I were to do it again I think I would go with the savvy shielding. I like their transmission brace that holds the transmission even when the shielding is removed for maintenance. http://shop.savvyoffroad.com/Under-Armor-Modular-for-03-06-Manual-or-Auto-UAM-Late.htm
