INSTALLATION INSTRUCTIONS
Note: If your truck bed is constructed of aluminum, use zinc rich primer to coat drilled holes.
Mounting the Front Leg Socket
Drill a pilot hole with a 7/32" drill bit in each marked hole. Then re-drill the
holes with a 1/2" drill bit. Install blind fasteners into each drilled hole.
Take the front leg socket assembly, four 5/16-18 x 1-1/4" hex head bolts, four
5/16" lock washers and four 5/16" at washers and install as shown above.
Tighten all screws at this point ensuring assembly is square and plumb to the
truck.
Take a 3/8-16 x 1" thread cutting bolt and install into the front mounting
bracket. Tighten the thread cutting bolt enough to mark the front leg socket for
drilling.
Disassemble the front leg socket assembly, take the front leg socket and drill a
pilot hole with a 7/32" drill bit through the mark created in the previous step by
the thread cutting bolt. Then re-drill the hole with a 1/2" drill bit. Reassemble
the front leg socket assembly to the truck bed tightening all hardware except the
3/8-16 x 1" thread cutting bolt.
Follow additional instructions if mounting to an aluminum truck
bed as explained in the Blind Fastener Installation on page 3.
ALUMINUM TRUCK BED INSTALLATION:
If installing on a 2004 Ford F-150 and newer vehicle, place
the F-150 Adaptor onto the front leg socket. Install and
tighten a 3/8-16 x 1" thread cutting bolt into the adaptor
to make a mark on the front leg socket. Remove adaptor
and drill a 7/16" pilot hole and then a 1/2" hole at the
indention mark of the thread cutting bolt on the leg socket.
Re-install the F150 adaptor onto the front leg socket. Do
not tighten the thread cutting bolt at this time.
Insert the front leg socket into the front mounting bracket
as shown in the gure below. Hold the mounting bracket
ush with the top rail of the truck bed ensuring the front
leg socket assembly is plumb and square to the truck bed.
Mark and center punch the four holes of the front mount-
ing bracket and front leg socket foot (see note above for
mounting to the truck bed oor).
• The illustrations show installation on the
passenger side of the vehicle. For installation on
the driver side, simply reverse the parts.
• If the pickup has a bed liner, the liner may
need to be drilled, trimmed or cut for proper
installation of the product.
• The best mounting hole location is between
oor ribs. A oor spacer and/or two extra 5/16"
washers have been provided to ll the void. If
possible, rotate the leg socket assembly 90
degrees to the rear of the vehicle.
