Step 1

Lower the exhaust by unhooking three rubber hangers, two by the muffler and one by the exhaust tip. Be sure to support the exhaust so as not to damage it.

Step 2

Using a 7mm socket, remove the eight screws from the underbody panel. Remove the plastic push pin to remove the underbody panel and set aside for later reinstallation.

Step 3

Remove the two factory bolts in the bottom of the frame using an 18mm socket. Next, remove the two factory bolts securing the rearward exhaust hanger bracket with a 10mm socket.

Step 4

Reverse fishwire the supplied 7/16” carriage bolts (#1) and spacers (#6) into the forward mounting points. Leave the fish wires attached.

Step 5

Using the tape measure and utility knife / aviation shears, mark and trim the bumper insert panel as shown. The panel may be removed if trimming is not desired by removing the two rivets at the bottom of the panel.

Step 6
Raise the hitch into position, threading the fish wires into the mounting holes and loosely installing the supplied M12 hex head cap screws (#2) and conical washers (#4). Remove the fish wires and install the 7/16” flange nuts (#3).
