Draw-Tite 4454 GOOSENECK RAIL KIT - Manual (Page 7)

9. 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. 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.
10. Drill 1/4” pilot holes (size will depend on width of blade in saber saw). 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.
11. Install the hitch into the opening.
12. Use the hitch as a guide to drill the 5/8” diameter holes for the forward cross member and the U-Bolt holes.
13.
Before installing the 5/8” carriage bolts through the hitch, the U-block shims (Part Number 5979) must be placed between the
hitch and 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.
14. Align the forward cross member with the 5/8 diameter drilled holes.
15. Install the 5/8 X 2.50 GR5 carriage bolts through the hitch, shims and cross members. Secure with lock washers and nuts.
Torque nuts to 150 ft.-lb. (203 N-m).
16. Install the (2) U-Bolts through the hitch and from under the vehicle install the large flat washer over the U-Bolt followed by a
spring, another large flat washer and secure with a thin 5/8” jam nut. Repeat for the other legs of the U-Bolts. The 5/8” jam
nuts are tightened until (3) threads are visible past the bottom of the jam nut.
17. Torque the 5/8 hex nuts, lock washers, and flat washers that attach the brackets to the forward cross member to 150 ft.-lb. (203
N-m).
