ADJUST THE LOCK RODS
Double-check both panels to ensure they open, close, lock and seal
correctly. If at any point the weatherstrip does not touch the bed rails,
readjust the lock rods and mounting brackets as needed.
12
Use an 1/8" hex key to loosen the
set screws on the linkages of the
driver-side lock rods.
8Position the lock rods tight
against the underside of the
angle iron (forward) and T-panel
gutter (rearward) so that they
draw the panels down and
compress the perimeter
weatherstrip. Tighten
the rod guide
brackets with a
7/16"socket.

Operating the access panels is easiest when
you press down as you open or close them.
Attach the gas springs to the ball studs.
13
Leave the cover closed and locked
for 24 hours to allow the weather-
strip adhesive, which is pres-
sure-sensitive, to fully cure.
14
To ensure the best weatherstrip adhesion, leave your
cover and tailgate closed for 24 hours after you’ve
made your final adjustments.
To avoid premature failure of your gas
springs, attach them barrel up, shaft down.
Repeat steps 8–10 for the passenger-side lock rods.

1/8"Hex Key
Adjust the length of the lock rods and retighten the set screws so that:
A. with the lock handle in the open position, the rod tips clear the
angle iron (forward) and the T-panel gutter (rearward),
B. with the handle in the closed position, the forward rod tip does
not strike the bulkhead, and
C. the rods point downward.
