General Instructions
1. Do not install mounting rails over plastic bed liners. Plastic bed liners must be cut out of the way to provide metal to metal
contact. Mounting rails may be installed on spray in liners
2. Use only bolts, nuts, and washers supplied to install this kit. All bolts are grade 5 and nuts are grade 5 unless specified
otherwise.
3. THESE INSTRUCTIONS ARE GUIDE LINES ONLY, ACTUAL INSTALLATION IS THE RESPONSIBILITY OF THE
INSTALLER AND THE OWNER. ALWAYS MEASURE TRUCK AND TRAILER BEFORE INSTALLING HITCH TO BE SURE
THAT THERE IS CLEARANCE AT THE CAB AND AT THE BUMPER TO ALLOW FOR TURNS.
Installation Instructions
1.
Lower and remove spare tire.
2. Remove emergency brake cable hanger in driver side wheel well and keep the hanger and the bolts.
3. Detach the 2 electrical harness hanger plugs from the inside driver side of the frame just rear of the fuel tank.
4. On 6’ truck boxes only and using a Saws All, cut off the extension attached to the truck box support beams and straddling the
frame of the truck. This is will insure that the frame brackets (A) and (B) can mount to the outside of the truck frame. Note: This
is not a structural part of the truck box and is only used by the manufacturer during assembly.
5. Place one mounting rail in the box of the truck, using your tape measure, center the rail between the weld seams on the length of
the truck box floor and the proper distance from the rear edge of the truck box as illustrated for options 1 and 2.
6. Mark and center punch the holes as per the illustrations. Move the rail out of the way and drill each position with a 1/8 ″ drill bit.
7. Temporarily position the frame bracket on the outside of the frame and check that the 1/8 ″ drilled holes align with the slots of the
frame bracket. Remove the frame bracket from the vehicle.
8. Enlarge the 1/8 ″ drilled holes to the hole sizes stated in the illustrations with the step drill.
9. When installing the bushings into the box supports, place the bushing on the ½” drill bit and insert them into the predrilled 3/4 “
hole. Drill a ½” hole thru the bottom of the box support using the bushing as a guide. When completed remove the drill and
bushing and re-drill the 1/2” hole with the 9/16” drill bit.
10. Loosely install the frame brackets by attaching the straps, collars, carriage bolts, brackets and nuts. (See illustration)
Note: Be sure to use the colored bushing and straps in the front and the black in the back. The front spacer strap (D) is only
required on the 1500 applications.
11. Loosely install the emergency brake cable hanger with the original hardware.
12. Move the mounting rail into position and rotate it up on its edge, insert the 4” long carriage bolts (2) into the rail and place the
front bushings (7) over the bolts. Holding on to the bushings rotate the rail into position while inserting the bushing and bolt into
the holes
13. Install the 2 ½” carriage bolts with the U-shaped spacer (8) to be located in the corrugation between the box and the mounting
rail. This insures a metal to metal contact. Attach with spacers and nuts as per the illustrations and tighten snug to keep the
mounting rail from moving.
14. Place the unassembled 5 th wheel saddles/slider/goose into the already installed mounting rail. Position the second mounting rail
with the saddles/slider/goose by inserting the tabs into the mounting rail and pushing the mounting rail tight towards the other
mounting rail. Ensure that the mounting rail is centered between the weld seams on the length of the truck box floor. This will
position the mounting rail in the correct location and ensure that the 5
th wheel will have a snug fit to the truck. NOTE: If more than
one hitch product will be used with the rails then both should be used at the same time to alien the second rail. This will ensure
that one product does not compromise the fit of the other.
15. Repeat steps 6, 8 and 13.
16. After fully installing the 50040 custom attachment brackets, tighten the fasteners in the following sequence. Note: Torque all
1/2 inch hardware to 72 ft-lbs. First torque the mounting rails to the frame brackets and then torque the frame brackets
to the truck frame.
17. Tighten the bolts securing the emergency brake cable hanger.
18. Secure the wire harness with the wire tie supplied
19. Reinstall spare tire.
Warning!!
When installing, during drilling protect the fuel tank by placing a piece of metal between the box support and the fuel tank on the
driver’s side. This will prevent drilling through the fuel tank. Be sure to use 4” carriage bolts here only.
