WARNING The fuel tank and/or other vehicle components are located below some of the holes. A
wood or metal shield must be placed between the frame and the fuel tank to prevent puncturing the
fuel tank when the drill breaks through the bed.
12. Drill 1/4” pilot holes (size will depend on width of blade in saber saw).
13. Cut out the truck bed and the bed hat section on short bed models from underneath the bed of the vehicle and file
edges as needed.
14. Install the hitch into the opening.
15. Use the hitch as a guide to drill the forward 5/8” diameter mounting holes. Also, drill 5/8” diameter U-Bolt holes if
installing a 6300 or 8339 gooseneck hitch.

the bed and between the cross members and the bottom of the bed. These shims are necessary to prevent the bed
corrugations from collapsing when the bolts are tightened.

nuts. Torque nuts to 150 ft.-lb. (203 N-m).
