ATTACH THE COVER & ADJUST THE LOCK RODS
If you have a 2005–2015 Tacoma, you should affix the included
10
bulkhead weatherstrip at this point. Refer to the Bulkhead Prep
Kit Installation Guide for details.
Place two G-200 cap clamps inside both side ends of the T panel,
11
their bottom halves fitting into the deck rail system. Tighten with a
9/16" socket.
Be careful that tightening the clamps does not deform
your bed rail caps.
Place the remaining two clamps under the cover at the nose of
12
the T panel, their bottom halves gripping the square-tube top rail
('16-up) or fitting into the deck rail system ('05-15). Tighten.
Retighten your clamps after 100 miles. Check them
every time you haul on top.
Close the tail panel. Loosen the set screws
13
on the tailgate-panel lock-rod linkages
with the 1/8" hex key.
ATTACH THE GAS SPRINGS
Attach the 30-lb gas springs to the cab-panel ball studs and the two
19
stronger gas springs to the tailgate-panel ball studs.
You'll find the strength of the gas springs
printed on the sides of the barrels.
To avoid premature failure of your gas springs, attach them
barrel up, shaft down.
Leave the cover closed and
20
locked for 24 hours to allow
the weatherstrip adhesive,
which is pressure-sensi-
tive, to fully cure.

1/8" hex key
Adjust the length of the lock rods and retighten the set screws so that:
14
A. with the lock handle in the open position, the rod tips clear the
striker brackets and
B. with the handle in the closed position, the rod tips do not strike
the bed walls.
With the lock handle in the
15
closed position, position the
lock rods tight against the
underside of the striker
brackets so that they'll draw
the panels down
and compress
the weatherstrip.
Tighten the rod
guide brackets
with a 7/16" socket.
Repeat steps 13 through 15 for the cab-panel lock rods so that:
16
A. with the lock handles in the open position, the rod tips clear
the deck rail system or square-tube top rail (forward) and
T-panel gutter (rearward),
B. with the handles in the closed position, the forward rod tips
do not strike the bulkhead,
C. the rods point downward, and
D. closing them draws the panels down & compresses the
weatherstrip.
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.
Double-check all three panels to ensure they open, close, lock &
17
seal correctly. If at any point the weatherstrip does not touch the
bed rails, adjust the position of the lock rods.
If you are also installing a Side Bin, do so now. Refer
18
to the Side Bin Installation Guide for details.
