That's not a skid plate. It's a "brush plate." That's the factory default unless you get the skid package. You can buy the metal plate from a dealer, or JustForJeeps.com or JParts.com. And while you're at it, you can get the fuel tank and transfer case skid plates, too. For the T-Case plate, you *have* to the the fuel tank skid, as the T-Case skid mounts to the F-Tank skid.
If that's not enough protection, go for the FrontGuard HC from 4xGuard.com.
