Helpful Hints
1. Install the Bulkhead Prep Kit before installing
your DiamondBack cover. Refer to the Bulkhead
Prep Kit Installation Guide for details.
3. If you are installing a Side-Loading ATV Carrier
on cargo bed longer than 6 feet, you must mount
the center panel adapter bars prior to installing
your DiamondBack HD. Refer to the Side Adapter
Bars Installation Guide for details.
2. If you are installing a Low-Profile Cab Guard
or HD Cab Guard, you should mount it prior to
installing your DiamondBack. Refer to the Cab
Guard Installation Guide for details.
POSITION THE PANELS
Finger-tighten the cap clamps at
each corner of the center panel.
2
To avoid hinge damage, do not close the
panel until hinges are fully mated: Tilt the
panel past 90° and push to the left until the
hinge lock tabs interlock.
The bottom halves of the cap
clamps should be in the deck
rail system.
Mating hinges is
easiest when you
line up the longer,
left hinge pin first.
4. It’s possible for one person to install a DiamondBack
solo, but the whole process, especially positioning
the panels and adjusting the lock rods, is much
easier with two people.
Repeat step three for the
tailgate panel.
4
Position the cover
front to back so that
the leading edge of the
cab panel lines up with
the leading edge of the
bulkhead.
5
CONTINUED ON OTHER SIDE
Place the center panel across the
center of bed, cheated slightly toward
the tailgate.
1
Make the sure the
arrow sticker on the
underside of the
center panel is
pointing toward the
tailgate.
Slide the cab panel onto the center panel by mating their hinges. Close the
cab panel slowly. Make sure it doesn’t hit your cab.
3
Center the DiamondBack cover
side to side on the truck.
6
Tighten the cap
clamps with a
9/16” socket.
7
Retighten your clamps after 100
miles. Check them every time
you haul on top.
