Installation Instructions

6. Install the center section, by sliding it
in from the backside over the axle then
aligning with the hole in the bed. Secure in
place.
7. On both sides of the center section, bolt
the cross members to the center section
with the supplied 1/2” hardware. Do not
fully tighten hardware.
4. On the inside of the bed, measure from the
rear (not the tailgate) forward 50-3/8” for a
8’ bed or 45-1/2” for a 6’-6” bed and mark.
Measure between the wheel wells and mark
center. Using a 5” holesaw, drill a hole thru
the bed.
Note: Using a board while drilling decreases
chances of the bit wobbling out of position
(left inset). It is also recomended to debur
the hole so the hitch will sit tight against the
bed (right inset).
5. Slide the cross members in from the side.
Push the flat end in just ahead of the rib.
Slide the angle in part way, lift up and
bend the rib then finish pushing it in, then
bend the rib back. Turn so that the holes
are on the lower side, facing down and to
the back.
Optional:
Loosen the bed bolts and lift the
bed to clear cross members.
