3. Line up the mounting holes in the frame brackets with the threaded studs on the ends of the cross members. Loosely
attach frame brackets to rails with 5/8 hex nuts, lock washers and flat washers as shown in Figure 1.
4. Use the U-Bolts to attach the frame brackets to the frame as shown in Figure 1. It may be necessary to loosen the
wire harness from the inside of the driver’s side frame in order to position the U-Bolts. The forward driver’s side U-
Bolt must go between the brake line and the vehicle frame Loosely fasten the U Bolts to the frame brackets using

5. With the cross members and side brackets installed, torque the 5/8-11 GR5 fasteners that attach the forward cross
member to the brackets to 150 ft.-lb (203 N-m). Torque the 1/2” fasteners and U-Bolt fasteners that attach the side
brackets to the frame to 75 lb.-ft. (102 N-m). The rearward cross member should be left loose until Step 15.
6a. For 6300 & 8339 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 4a. Not all holes can be drilled from under the vehicle, but
should be done later from inside the bed.
Bolt must go between the brake line and the vehicle frame. Loosely fasten the U-Bolts to the frame brackets using
the 1/2” nuts and conical toothed washers. Fish wire the 1/2-13 carriage bolts and 1/4 X 1.00 X 3.00 blocks through
the holes in the vehicle frame and through the flange on the frame brackets. Loosely install the 1/2 conical toothed
washers and hex nuts.

6b. For 83391& 83399 use the inner 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 4b. Not all holes can be drilled from under the vehicle, but
should be done later from inside the bed.
7. Align the holes on the template (provided with the gooseneck hitch) with the holes 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 (see Figure 5). If the vehicle is equipped with a bed liner, a section of the bed
liner must be cut away so that the gooseneck platform can contact the bed corrugations.
8. Drill 1/4” pilot holes (size will depend on width of blade in saber saw).
