4. Line up the base rail and the plastic shim so that the
holes line up – the thick side of the shim should face out-
wards. (Certain truck models do not require the plastic
shim. See table on page 5 for details). Insert one plastic
washer onto each 3/8-16 x 3” socket head cap screw.
Insert the socket head cap screws through the base rail
holes, through the shim and
through the rubber expansion
blocks, as shown below. Hand
as shown below as shown below
tighten the brass pocket nuts
just enough to hold the rub-
ber expansion blocks in place
against the shim (without com-
pressing the rubber block).
Tip: Tape or glue the brass pocket
nuts to the rubber expansion
blocks before inserting them into
the stake pockets of the truck.
This will stop the nuts from drop-
ping into the stake pockets if you
ever need to loosen and remove
the rails.
5. Insert the rubber block assem-
bly into the stake pockets of
the vehicle (the rubber blocks
fit right into the stake pockets).
Repeat the process for the
other base rail.
NOTE: For trucks without stake pockets, refer to notes
on page 7.
6. Base rails must be parallel and in plane.
Parallel (Straight): Before tightening, measure the inside
Parallel Parallel
width, from rail to rail, using the T-Tracks of each base rail
at the same location front and rear. Measurements are to
be equal within 1/16”: adjust as required.
In plane (Flat): Use a straight edge or the crossbar
to ensure base rails remain level. The straight edge
should touch all four tracks, within 1/16”. If not,
adjust the shims, or use the supplied rubber tape strips
to level out the base rails.
7. Partially tighten the block assemblies at the cab end
of the truck, (left & right sides), using a 5/16” socket
wrench on the ball point allen driver supplied. Press
downwards to keep the rail in position as you tighten.
(Note: The “ball” of the allen driver should be inserted
into the socket of the bolt). Repeat steps 7 for the tail-
gate end.
8. Re-measure to verify that the base rails have remained
parallel and flat, then fully tighten cab and tailgate
assemblies to a torque specification of 9 ft. lbs.
(Note: To ensure the base rail remain Parallel and In Plane,
keep straight edge on tracks until rails have been complete-
ly installed. The flatter and straighter they are, the better
the slide!)
9. After the base rails are secured in the front and rear,
tighten the middle stake pocket assembly. Middle stake
pocket assemblies are required on 8’ beds only.
10. Tighten all stake pocket assemblies to a torque specifi-
cation of 9 ft. lbs.
CAUTION: For proper installation, use a torque wrench
(not included) to verify the torque spec.
11. Thread and tighten (4) 1/4-20 x 3/8” safety bolts onto
the “T”s at the cab end of the base rails.
CAUTION: All safety bolts must be installed, and all knobs
tightened, prior to operating the vehicle on the road.
Now you’re ready for the overhead rack assembly.
For good performance and safety, periodically check that
the base rails remain parallel and secure. Re-torque all fas-
teners to the proper specification after the first 500 miles,
and every 10,000 miles thereafter.
Please review the enclosed CAUTION sheet for additional
guidelines.
