Diamondback HD User manual

Remove the trio of factory bolts that rununder the bed rail along the
length of the driver-side cargo bed wall using aT30 Torx wrench.
Repeat steps 1–2 on the passenger side.
PRE-INSTALLATION NOTES:
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.
If you are installing a cab guard or headache rack, you should
mount it prior to mounting your DiamondBack cover. Refer to its
installation guide for details.
4Place the center panel across
the center of bed, cheated
slightly toward the tailgate.
Make the sure the
arrow sticker on the
underside of the
center panel is
pointing toward the
tailgate.

PREPARE THE CARGO BED & ATTACH THE COVER
1
Use those bolts to fasten a mounting bracket to the wall, its
clamp strip up and jutting inward.
2
3
Loosely affix the center panel to the truck by finger-tight-
ening a cap clamp at each of the four interior corners of
the underside of the center panel.
5
Attach the tail panel by angling it 90° from the bed rails, sliding its
driver-side, loop-shaped hinge knuckle fully onto the corresponding
center-panel hinge pin, then dropping its passenger-side, C-shaped
hinge knuckle fully onto its corresponding pin.
6
FIRST SECOND
Lower the tail panel into the closed position.

Center the cover side to side on
the truck.

Tighten the cap
clamps with a
9/16" socket.
Road vibration can loosen your clamps. Retighten them after
100 miles. Check them every time you haul on top.
9Position the cover
front to back so that
the leading edge of
the closed cab panel
clears the cab
window frame by
about a quarter inch.
Adjust the length of the tailgate-panel lock rods and retighten their
set screws so that:
A. with the lock handle in the open position, the rod tips clear
the mounting brackets,
B. with the handle in the closed position, the rod tips do not
strike the mounting brackets, and
C. the first bend in the rods point downward.

ADJUST THE LOCK RODS
12 Loosen the set screws on the
tailgate-panel lock-rod linkages.
To get the weatherstrip compression neces-
sary for its adhesive to cure and for the cover
to keep out the weather, have a second person
press down on the cover while you’re adjusting
the lock rods.
Operating the access panels is easiest when
you press down as you open or close them.
Repeat steps 12 through 14 for
the cab panel.
Your panels should be difficult to operate at first. After finishing
installation below, leave the panels closed as much as possible for
3–4 days to break in the weatherstrip. After that period, you
should find that the panels open and close without difficulty.
With the lock handle in the
closed position, position the lock
rods tight against the underside
of the mounting-bracket shelf so
that they’ll draw the
panels down and
compress the weath-
erstrip. Tighten the rod
guide brackets with a
7/16" socket.

To avoid premature
failure of your gas
springs, attach them
barrel up, shaft down.
If some of your gas springs
have heavier poundage
printed on their sides than
others, use the stronger
ones on the cab panel.
