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.

Sheet 7 of 9 4449N 5/29/14 Rev. C

5. Loosely install the driver’s side and passenger’s side hitch side brackets by attaching the 5/8” hardware to the threaded studs.

Install the 5/8 X 3.00 carriage bolts through the hitch side brackets, 5/8” blocks and large slots in the vehicle frame rails.

Loosely, install the 5/8” conical toothed washers and 5/8” hex nuts onto the carriage bolts (see Figure 1).

6. Use the supplied U-Bolt for the forward attachment of the bracket to the frame (see Figure 4). Position U-Bolt from the inside

of the vehicle frame pointing towards the hitch side bracket. On the passenger’s side of the vehicle, the U-Bolt must be

positioned to the vehicle forward side of the shock mount and installed on an angle through the mounting slots on the hitch side

bracket.

7. Torque the 5/8-11 GR5 fasteners connecting the forward cross member to the brackets to 150 ft.-lb. (203 N-m). Torque the ½-

13 U-Bolt fasteners to 75 ft.-lb. (102 N-m). Torque the 5/8 nuts to the 5/8 X 3.00 carriage bolts to 150 ft.-lb. (203 N-m). The

rearward cross member should be left loose until step 17.

8. Use the outer edges of the long slots in the forward cross member as a template to drill 5/8” diameter holes through the truck

bed as shown in Figure 5. Not all holes can be drilled from under the vehicle, but will be done later from inside the bed.

9. Align the holes on the template (provided with the gooseneck hitch) with the hole previously drilled through the bed. Be sure

that the template is properly oriented toward the front of the vehicle. Center punch the holes that will be used to cut the

opening in the bed. If the vehicle is equipped with a bed liner, a section of the bed liner must be cut away so that the gooseneck

hitch can contact the bed corrugations.

10. Drill 1/4” pilot holes (size will depend on width of blade in saber saw). Cut out the truck bed, file the edges as needed.

11. Install the hitch into the opening.
