skid plates picture
my truck has to oem skid plates on it and it has two one under the oil pan and one under the transfer case...none on the gas tank or any suspension. my jeep oem skid plates covered a lot more but it was also a little lower than my truck so far i haven't hit nething under there...so u are missing the one under the oil pan...previous owner prob took it out when he changed the oil the first time but never put it back on...u dont have to do this but it makes it a little easier if u dont have lift for ur oil change
About a week after buying my truck and looking at the window sticker it was supposed to have the skid plates with the TRX package but there are none on my truck. Either they were never installed or the previous owner which only put 7000 miles on the truck removed them, which I doubt.
The TRX4 package does not include skid plates you have to have the TRX4 Offroad package to get them
