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.

3. 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 and above the exhaust.

supports over the rear axle, and another notch in front of the forward bed support as shown in Figure 7. Another way pp , pp g y
to notch the bed flange is to make a single vertical cut, then fold the flange material up enough to allow the for the
rails to fit between the frame and the bed. After the rails have been installed, the cut flange may be bent back down to
its original position and the cut steel surfaces may be touched up with paint to prevent rusting.
5. Slide the forward cross member through the forward notch underneath the bed, and over the frame until it completely
spans the passenger’s and driver’s side frame rails.
6. Slide the rear cross member through the notch between the two bed supports, underneath the bed, and over the frame,
