ASSEMBLY
1Start by loosely mounting the top rail to the corresponding front and rear
legs using the 5/16”-18 x 3/4” button head bolts and 5/16”-18 serr. flange
nuts. The side rail should sit on the top of the legs with the small slotted
flange pointing down along the side of the legs. The side rail bolts into the
top of each leg as well as the side of each leg. Make sure that you have the
legs oriented so that if you were to set them onto the side of the bed, the
wing of the rear leg and the mounting plate of the front leg are towards
the rear. Also, make sure that the top edge of the side rail is angled towards
the front so that the top edge hangs over the front of the front leg.

ASSEMBLY
2Next, mount two of the wider bars between the front and rear legs using
the 5/16”-18 x 3/4” button head bolts, 1/4” washers and 5/16”-18 serr.
flange nuts. You will see that there are several mounting options for this
bar. The position that you put these bars in will be dependent on if and
where you want the doors to be installed and which way you want them
to open. If you want the door to open up, you can put this bar in the top
or bottom slot. If you want the door to open down, you will have to put
this bar in the top slot. Once you have that tightened into place, you can
tighten the bolts on the top rail as well.

ASSEMBLY
3Next, connect the two sides you assembled together using the thinner
cross bars with 5/16”-18 x 3/4” button head bolts and 5/16”-18 serr. flange
nuts to mount them in position. One bar will mount to the front of the top
rail, and one will mount to the rear. The open side should be on the bottom.

ASSEMBLY
4Next, mount the two remaining wider bars to the top of the rack between
the bars you just installed. Do this using the 5/16”-18 x 3/4” button head
bolts and 5/16”-18 serr. flange nuts. Which slots you mount them to is up
to you and what you plan to use them for. Shown below is an image of the
passenger side bar being installed from an underside view.

5
ASSEMBLY
With the rack assembled, you can place it onto the bed of your vehicle.
How you mount it depends on whether or not you have the trail rail
system in the bed of your Gladiator. If you do, simply insert a
5/16”-18 x 1-1/2” carriage bolt through each hole in the small rectangular
spacer and slide that into the trail rail. Do that three more times, then you
can mount the legs of the bed rack using the 1/4” washers and 5/16”-18
flanged nylock nuts.

ASSEMBLY
6If you do not have the trail rail, you will need to clamp the legs to the bed,
to do so, loosely attach the c shaped bracket to the back of the bottom of
each of the legs using the 5/16”-18 x 1-1/2” carriage bolts and
5/16”-18 flanged nylock nuts. Make sure the 90-degree bend is on the
bottom and the carriage bolts go through the back side of the c shaped
bracket. Finally, push the c shaped brackets up until the edge of the bed is
between the brackets and the bottom of the legs and tighten them all into
place, clamping the bed rack onto the bed. Try to tighten each bolt evenly
in order to best secure the bed rack.

7
ASSEMBLY
With the rack and so topper in place, you can install the corner support
brackets using the 5/16”-18 x 3/4” button head bolts and 5/16”-18 serr.
flange nuts. The rear bracket is the one with the hole cut out of the middle
of it. The rear brackets mount to the slots on the inside of the leg and the
inside of the top cross bar. Make sure that the bolts going into the rear leg
go out through the inside of the rear leg so that you have room to get to
the head of the bolt. The front brackets can mount to the inside or outside,
but we recommend mounting them to the outside because it can be easier.

8
ASSEMBLY
Next you can get started on installing the doors if you are choosing to do
so. Start by installing the triangular hinge brackets into the slots necessary
for where you want your doors on the inside of the legs using the
5/16”-18 x 3/4” button head bolts and 5/16”-18 serr. flange nuts. If you
want the door to flip down, install them in the bottom slots. If you want
the door to be above the side bar and flip up, install them in the top slots. If
you want the door to be below the side bar and flip up, install them in the
second slots from the top. No matter where you put the hinges, make sure
that the hole that mounts the door is towards the top and outside of the
rack. Shown below is an image of the installation of a hinge for a door that
flips up, above the side bar.

9
ASSEMBLY
Next, mount the latch brackets roughly where the latch of the door will
land when closed. You will most likely need to move them later so just
get them in the general area. The latch brackets should be positioned so
that when they are bolted into place, the other side sticks in towards the
door and then out towards the outside of the rack. Either before or aer
mounting the latch bracket, insert the 5/16” rubber bumpers into each of
the two small hole in each bracket. Make sure the cushion part sits where
the edge of the door will land.

10
ASSEMBLY
Next, mount the latches to the holes in the doors. To do this, start by
removing the metal back cover from the latch. Then, put the latch into the
hole in the door through the front and place the metal back piece back
onto the latch from the inside of the door, sandwiching the door between
them. Then, use the provided bolt, washer and lock washers to tighten the
back against the inside of the door.

11
ASSEMBLY
Next, mount the doors to the hinges using the 5/16”-18 x 3/4” button
head bolts, 5/16” nylon washers and 5/16”-18 nylock nuts. The door bolts
in between the hinges with a nylon washer between the hinge and the
door as well as the door and the nut. You will want to tighten the bolts to
the point that they won’t rattle, but you are still able to rotate the door.

12
ASSEMBLY
Next, attach either the gas struts or the lanyards depending on which way
your door is going to open. If it is going to open up, you will need to attach
the gas struts (step 13). If it is going to open down, you will need to attach
the lanyards (step 14).
13 For the door that opens up, pull the top bolt out of the latch bracket and
bolt the gas strut in through that hole using the threaded end and a 5/16”-
18 serr. flange nut. Then attach the other end to the large hole in the door
using a 5/16”-18 X 1” button head bolt, three nylon washers and a nylock
nut. One washer goes between the head of the bolt and the door and the
other two go between the door and the strut.

14
ASSEMBLY
For the door opens down, attach one end of the lanyard to the hole in
the middle of the leg using a 10-24 X 3/4” button head bolt, a #10 nylon
washer and a 10-24 nylock nut. Then attach the other end to the inside of
the door using the same hardware. Make sure the flat end of the eye of the
lanyard sits against the nylon washer. The dierent holes in the door are
there to give you options for how wide you want it to open.

15
ASSEMBLY
Next, if you have installed a so topper, undo the nuts on the bolts for the
clamps on leg. Next, place the hook shaped so topper bracket into the
hole in the rail of the so topper and hold the other so topper bracket
underneath it so that the holes on the two line up and the carriage bolts
go through the slots in the bottom bracket. Once they are oriented
correctly, move the bottom bracket roughly 1/8” down and tighten it into
place. Then, with the upper bracket still hooked into the channel on the
so topper, use a
5/16”-18 X 3/4” bolt, M8 washer and 5/16”-18 nylock nut to tighten the
two so topper brackets together. Make sure that they sit flat against each
other. We recommend getting some rubber weather stripping to line the
bottom edge of the so top in order to get it as weather tight as possible.
