1. Place the two bed rails across the truck bed between the wheel wells. Position the 5th wheel uprights between the bed rails
so that the tabs in the base of each upright will fit into the slots in the ends of the bed rails. Secure the uprights in place
with the rail hitch pins and hair pins supplied with the 5th wheel installation kit. Securely attach 5th wheel cross member to
uprights.
2. Position the bed rail assembly in truck bed as shown in Figure 2. When hitch is correctly positioned in the bed and the bed
rails are parallel, mark four attachment points on the truck bed using the 5/8” square holes indicated on the layout in
Figure 2. Check below the bed before drilling holes to see that all wiring, brake lines or other obstructions are moved out
of the way and will not be contacted by the drill. Move the hitch assembly out of the way and drill four 5/8” diameter
attachment holes down through the bed at the previously marked points.
3. Reposition the bed rails in the bed so that the square 5/8” hole in the end of each rail is lined up over the drilled holes.
Place item #6 (1” spacer tube) under ends of each bed rail, in line with the drilled holes as shown on Figure 3.
4. If the bed corrugation above the frame is UP, leaving a space above the frame bracket, place item #7 (spacer plate) in the
bed, under the base rail as shown on Figure 4.
5. If wheel well is lined with a plastic liner that covers the frame, then cut out enough of the liner to expose the frame for
bracket installation.
6. Place item #13 (lock washer) and item #14 (flat washer) onto item #15 (5/8" hex bolt) and then insert into 4 drilled holes
through the base rails.

7. Position item #1 (DS Front "L" Bracket) and item #2 (DS Rear "L" Bracket) up against the outer surface of the truck
frame with the long slotted part of the bracket positioned over the frame and under the bed and guide the 5/8" hex bolts
that were installed in step 6 through the long slots in the brackets. Brackets are marked with a DSF for driver side front or
DSR for driver side rear to ensure brackets are placed in the correct position of the frame. Thread item #5 (Clip Nut 5/8-
11) onto end of item #15 (5/8-11 Hex Head Bolt) until all the long slotted portion of the brackets come in contact with the
underside of the bed floor. See Figure 4 & 4.1.
8. Press the frame brackets up against the truck frame until they come in contact and stop. Look through the holes
in the frame brackets and make sure the holes in the frame are in line, you may have to loosen the 5/8" hex bolts
some.

Continue to retrieve pull wire until bolt appears through slot in bracket, carefully un-thread pull wire from bolt
and place item #11 (flat washer), item #10 (lock washer) and item #9 (5/8 hex nut) on bolt and finger tighten only
at this time.
10. Repeat step 9 for the remaining slot in the driver side bracket, driver side rear bracket, passenger side front
and rear brackets.
11. Tighten each 5/8” bed rail attachment bolt to 150 ft-lbs. torque. Failure to tighten bolts as described may result
in fastener loss or failure. DO NOT apply torque to the nut portion of the clip nuts (#5). You will DAMAGE it.
12. Check each rail hitch pin for freedom of movement in the bed rail connection before tightening the 5/8” bolts
and nuts. Adjust uprights, if necessary, by placing shim 31582 or 30243 between the upright and the cross
member to obtain free pin movement. See Figure 5. Shims 31582 & 30243 sold separately.
