Today I installed the Offroad Evolution skid plates. The first one to be installed was the oil pan skid. I removed all of the bolts to the oil pan (after draining the oil) and reinstall the bolts after putting the skid in place. Next I installed the transmission skidplate, and attached it to the oil pan skid. Last was the new center section skid plate which protects the exhaust and adds strength under the transfer case.
