WARNING:
Most trucks have fuel lines, brake lines,
electrical wires or other vehicle systems located along
the frame rails or in the general area where
Turnoverball hitches install. Carefully examine the
locations of these systems before installation. Make
certain that these are not damaged during positioning
hitch components, drilling holes, or tightening
fasteners. Damage to these systems may result in
property damage, serious injury, or death.
INSTALL CROSS MEMBERS
PAGE 3 of 6
Cross member installation location.
The cross
members for this hitch installation are designed to rest
on top of the truck frame and mount to existing
threaded holes on the top of the frame rail. To make
installation as easy as possible, locate and familiarize
yourself with these threaded holes before installing the
cross members. See Figure B1 for a top down view of
the frame with the cross members installed.
Place the forward cross member.
Under the truck,
lift the end of the cross member assembly without the
cross member bracket over the exhaust towards the
passenger side shock mount, as shown in Figure B3.
Bring the cross member bracket over the brake line
bracket on the driver side of the truck and rest the flat
end of the cross member bracket on the frame. Move
the cross member so the end of the cross member
assembly with no cross member bracket is resting on
the exhaust.
Complete the cross member assembly.
Pass a
cross member bracket between the exhaust and the
passenger side of the frame, see Figure B4. The flat
end of the cross member bracket will go over the
frame and the other side will bolt up to the cross
member. Bolt the two parts together so the
connections match the other side of the cross member.
Once assembled move the cross member assembly so
its just forward of the mounting holes in the frame, see
Figure B5. Hand tighten hardware only at this time.
Place the rear cross member.
Attach another cross
member bracket to the remaining cross member as
shown in Figure B2, leave the 5/8" bolts loose.
Position the cross member behind the bed cross
member and 4" hole drilled in the bed, see Figure B6.
Attach a second cross member bracket to the cross
member as shown in Figures B4 & B5. Hand tighten
hardware only at this time.

WARNING:
Turnoverball hitch components are heavy
and may be cumbersome to handle. Failure to use
proper lifting techniques and caution when handling
these items could result in serious injury.
Prepare a lifting device (optional).
The purpose of the device is to
safely hold the hitch in position
during part of the installation. See
Figure A3 for an example. A simple
mechanical lifting device is available
for purchase from B&W.

Locate parts and hardware.
Locate the two cross
members and the four cross member brackets. These
will be assembled together using 5/8" x 4−1/2" flange
bolts and 5/8" flange nuts, see Figure B1.
Forward cross member assembly.
Inspect one of
the cross member tubes, find the wall that contains
the welded seam. Bring a cross member bracket
and cross member together so that the tubing wall
that contains the welded seam is down inside the
cross member bracket, see Figure B2. Attach the
cross member bracket to the cross member by
passing the 5/8" bolts through the two parts, as
shown in Figure B2. Align the bolts so they are
centered in the cross member brackets slots. Attach
each bolt with a 5/8" flange nut. Push the cross
member tightly into the cross member bracket so
there is no gap between the two parts. Tighten and
torque the 5/8" nuts to 150 ft. lbs.
