Rock Hard 4x4 Parts JK Oil Pan, Transmission and Dual Catalytic Converter Skid Plate fastens to the frame in front of both motor mounts and at the main crossover in the rear for maximum protection. An extension on the left-hand side protects the normally exposed converter which would be a very expensive fix if damaged. Also, to make oil changes easy and to minimize clean-up, this skid plate comes complete with an oil drain access plate. All bolts at the frame crossover are replaced with tapered bolt head protectors to allow rocks to slide across them with ease and still allow you to get a socket on the bolt heads for removal. Our tests have shown stock drive lines to clear this skid at 40" of flex. Fits 2007-2014.
