OEM gas tank skid is light gauge and bends easily. Aftermarket skids (Rocky Road, Skid Row) are 3/16" or 1/4" steel and worth every penny on rocks.
The OEM gas tank skid is 14-gauge steel that protects against branches and curbs but folds on a real rock. A holed gas tank on the trail is a bad day — the XJ tank sits low and exposed.
Aftermarket replacements:
Install is straightforward — drop the OEM skid (six bolts), bolt the new one up. The aftermarket plates typically reuse the factory mount holes plus add a couple of body mount captured nuts for extra rigidity.
While you're under there: inspect the tank straps (rust through), filler neck hose (gets crispy), and rollover valve at top of tank. Replace the straps if rusty — they're cheap ($30) and a broken strap means a fallen tank on the trail.
Cross-reference: see armor section for full underbody skid kits that include this plus oil pan, t-case, and rocker protection.
