MOUNTING KIT
General Notes
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 hardware supplied in this or the 30153 kit to install this Custom Quick Install Mounting Kit. All bolts are grade 8 and
nuts are grade 5 unless otherwise specified.
3. These instructions are guidelines 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.
4. DO NOT INSTALL THIS PRODUCT ON OR ATTEMPT TO TOW WITH A TRUCK WITH A BED THAT IS LESS
THAN 6’ LONG UNLESS A SIDEWINDER PINBOX COUPLER HAS BEEN INSTALLED ON THE TRAILER.
Installation Instructions
1. Lower and remove spare tire. Remove exhaust heat shield from the underneath the passenger side of the vehicle.
2. On Pickups with OE Trailer Brake Controller: Relocate the electrical plug that is located on the inside of the driver’s side
frame rail over the rear wheel (Figure 2a). The plug may be removed from the frame by loosening the two bolts on the outside
of the frame and pushing the bolt heads through the key hole slots, as shown in Figure 2b. Attach the plug to the angle bracket
supplied with the mounting kit. The bracket will be attached to the inside of the frame with a 5/8” bolt at a later installation
step.
3. Place one mounting rail in the bed of the vehicle. Center the rail on the floor of the truck bed and use your tape measure to
locate the proper distance from the rail to the to the rear edge of the truck box as illustrated on page 3.
4. Use a center punch to mark the holes in the rail per the illustration. Move the rail out of the way and drill each position with a
1/8” drill bit. Note: When drilling holes through the bed be sure what is below the truck bed in those locations.
5. Temporarily position the frame brackets on the sides of the frame and check that the 1/8” drilled holes align with the slots in
the frame brackets. Remove the frame brackets from the vehicle.
6. Enlarge the 1/8” drilled holes to 9/16”.
7. Fasten the frame brackets to the vehicle frame rails as shown in Figure 1. Pass the cap head bolt through the 1.75” flat washer
and then the rearward slot interior of the truck frame. Place the mounting bracket, 1.3125” flat washer, and the nylon lock nut
on and hand tighten. On Pickups with OE Brake Controller, refer to installation step 2 to relocate the plug with the angle
bracket. Use the 5/8” X 1.75” bolt to attach the angle bracket to the inside of the frame (see Figure 2c) , the angle bracket will
go between the flat washer and the frame
8. The forward slot of the truck frame will require using the supplied wire pull to install the carriage bolt to the interior of the
truck frame. Pass the wound end of the wire through the exterior of the frame, pulling it enough to thread the rectangular
locking spacer and the 5/8” carriage bolt on to the wire pull. Pulling the wire pull back through the frame will allow the
installation of the mounting bracket, 1.3125” flat washer and the nylon lock nut. Hand tighten the nut in place.
9. Reposition the mounting rail over the holes in the bed and fasten the mounting rail to the frame brackets using the hardware
supplied with the rail kit. Use the U-shaped blocks between the frame bracket or mounting rails and the truck bed to ensure
metal to metal contact. Install center bolt and hand tighten.
10. Place the unassembled 5th wheel support arches/slider/goose into the already installed mounting rail. Position the rearward
mounting rail with the support arches/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 on the bed of the vehicle. This will position the
rail in the correct location and ensure that the 5th wheel will have a snug fit to the truck. Note: If more than one hitch product
will be used with the mounting rails then both types should be used at the same time to align the rearward mounting rail. This
will ensure that one product does not compromise the fit of the other.
11. Repeat installation steps 4, 6 and 9.
12. Starting with the hardware that fasten the mounting brackets to the frame torque all the nuts. Torque the 1/2” fasteners to
110ft-lbS (149N*M), and the 5/8” bolts to 212 ft-lbs (287N*M).
13. Re-install spare tire.
