Short & Long Bed
6300 / 630044 / 8339 GOOSENECK HITCH INSTALLATION
NOTES:
This section of instructions refers to installing the 6300, 630044 or 8339 head only.
Always make sure the ball is fully locked before towing.
Keep the ball and ball pocket well lubricated.
Periodically re-torque all the hitch fasteners.
Check ball, hitch coupler, safety chains and other connections for proper operation every time you tow.
Warning:
The tow vehicle manufacturers recommended towing capacities should UNDER NO CIRCUMSTANCES be
exceeded.
Check for adequate clearance between the gooseneck trailer and the rear of the cab and the rear of the truck box
before installing hitch.
All trucks have fuel lines, brake lines and electrical wiring located along the vehicle frame where the rail kit
installs. Carefully examine the location of fuel lines, brake lines and electrical wires before installation and be
certain not to damage these when positioning the hitch components. Be careful when drilling holes, cutting
sheet metal and tightening fasteners as to not limit the integrity of these systems.
1. From underneath the passenger’s side of the vehicle, remove or cut out the section of the heat shield that
is located under the bed, above the exhaust, and between the two bed supports. On 6’-6” bed models the
section of the heat shield located between the rear bed support and the spare tire will also need to be
removed.

2. On short bed models, cut the heat shield on the gas tank or bend the top edge about 1” down to make
