INSTALLATION INSTRUCTIONS:
1. Locate all parts to become familiar with all brackets.
2. Find drivers side front frame plate. Both holes in frame will need to be drilled out to 17/32”. Locate
frame bracket as shown in photos on page 3. Mark and drill holes. 1/4” pilot hole is recommended. Both
of these holes will need to have 1/2” x 2” hex bolts with star and flat washers
(see page 5 for bolt washer
assembly)
fished into them with supplied bolt fisher. (Make sure the bolts are perpendicular to the frame
before tightening). When fishing these bolts put the coiled end of the bolt fisher into one of the holes and
bring it out of the frame. Insert the threaded end of the bolt onto the fisher and slowly remove the fisher,
pulling the threaded end back through the desired hole. Hint: Do not force the bolt by pulling hard, or
jerking on the fisher, as this will likely damage the fisher, and/or drop the bolt in to the frame. (see
our bolt fishing guide). After both bolts are fished into the frame plate, install flat washer, lock washer,
and nut onto these bolts and tighten to 60 ft lbs.
Warning: make sure all wire harnesses, brake, and fuel lines are clear when tightening. Damage
may occur.
3. Locate tie down receiver and attach to frame plate using a 1/2” x 3” hex bolt and locking nut. Tighten
nut until tie down receiver can be moved but will stay in whatever position you set it.
4. Identify upper channel. Looking up at the bottom of the truck box, remove the factory bolt that attaches
the truck box to the frame tower. Install the upper support channel and reinstall the factory bolt.
It is nor-
mal to have a gap between the tie down upper support channel and the truck box channel. This gap
will be eliminated when the fasteners are torqued.

.
Do not drill out the 7/16” hole as you will not use the 3/8” bolt.
Now drill out the remaining 7/16
” hole and fish the 1 1/4” x 3/8” hex bolt and flat washer in through the end of the box channel with the
supplied bolt fisher. Install flat washer, lock washer, and nut. Tighten to 35ft lbs. Make sure to keep upper
support channel parallel with the box channel (refer to photos on page 4).
5. Find one bent insert and 1/4” pin and put the bent insert into the tie down receiver using the first hole in
the insert. Install 1/4” pin.
6. Locate upper support strap and two 1/2” x 3” hex bolts and two locking nuts. Choose the appropriate
holes in the upper and lower channel to give at least 1” clearance between the insert and the lip of the box
or after market accessory. Tighten to 60 ft lbs. See page 6 for correct strap angle information.
IMPOR-
TANT! Tighten all fasteners until there is no slack or play between any component.
7. Double-check that all bolts are tight and that there is 1” of clearance between the insert and truckbed lip.
*NOTE
: The included tie down inserts come with 2 predrilled pin hole locations. When hooking up
your camper, either hole may be used providing there is a MINIMUM
of 2” clearance between the
chain/turnbuckle attaching assembly and the truck bed wall.
