BEFORE INSTALLING

OVERHEAD LIFTING DEVICE

An overhead-lifting device, such as chain falls, engine hoist, or cable come-a-long, can be used to lift the center section of the

hitch in place. Lower a loop of rope or chain through the 4” hole in the truck bed oor and attach it to the latch pin in the round

hitch receiver tube in the center section. Use the lifting device to raise the center section until the round hitch receiver tube that

protrudes from the center section ts in the 4” hole in the truck bed oor. Maintaining upward pressure may facilitate fastening the
crossmember to the center section, especially if the truck bed oor has been distorted downward from heavy use. If you use an

overhead-lifting device, it should be disconnected before squaring the center section across the frame, installing the sideplates and
torquing fasteners.

WARNING

Most trucks have FUEL LINES and/or BRAKE LINES and/or ELECTRICAL WIRES located along the frame rails where B&W Turnover­ball™ hitches install. Carefully examine the location of fuel lines, brake lines and electrical wires BEFORE INSTALLATION. Be certain
you will not damage fuel lines, brake lines or electrical wires when positioning hitch components, drilling holes and tightening fas­teners. The fuel tank vent, located on top of the gas tank, can be easily damaged during the installation of the hitch components.
Care must be taken when positioning the front crossmember and center section components.

WARNING

On Short bed trucks, BEFORE INSTALLING THIS HITCH, check for adequate turning clearance between the front of all
of your trailers and the truck cab.

WARNING

DO NOT invert the ball in the socket when carrying heavy loads on 2 wheel drive trucks. The ball may hit the top of
the differential. Remove the ball from the socket before loading. A plug for the socket is available from B & W.

INSTALLATION INSTRUCTIONS

STEP ONE - REMOVE SPARE TIRE AND HEAT SHIELD

The heat shield under the bed oor must either be removed or a section cut out for

the hitch assembly to be installed.

A) Remove the heat shield from in front of the back crossmember.
B) Remove the heat shield from the back of the crossmember located near the

front of the wheel well.

STEP TWO - REMOVE EXHAUST BRACKET

To ease installation of the center section it is necessary to remove the lower exhaust
bracket. Simply pull the hanger rod out of the rubber bracket hole, a 6” to 8” wood
block can then be positioned between the exhaust pipe and frame of the truck. This
will increase your clearance between the top of the exhaust pipe and the bottom of
the truck bed oor. (Caution: Exhaust pipe may be hot).

STEP THREE- MARKING AND CUTTING 4 INCH HOLE IN TRUCK BED

Begin by verifying and measuring the correct hole location in the truck bed oor. Measure from the back end (tailgate
end) of the truck bed oor by hooking a tape measure over the back of the truck box and mark the oor at the correct

measurement. Next, center the location between the wheel wells. This will be the center point for the four inch hole.
This location is critical to the correct installation of this hitch, so measure, mark and saw carefully. If the truck has

a plastic bed liner, you may drill through both, but it is more difcult to accurately locate the midpoint between the

fender wheel wells, and to be sure that the bed liner does not move while sawing the hole. Make a 4 inch hole at this
location using a four inch hole saw, or by marking a 4 inch circle and cutting it out with a saber saw equipped with a
metal cutting blade.

TIP: B&W us es a 3 /4”
pi e ce o f ply wood as a
drilling guide to prevent
the hole saw from moving
while drilling the 4” hole
in the bed.

STEP FOUR-CROSS MEMBER INSTALLATION

Install the two cross members. They will be installed by sliding them from inside the wheel well, above the tire, through
the gap between the bed and the truck’s frame and across until they span the frame
rails. The gap between the bed and frame is large enough to allow this, but the gap

is partially obstructed by a sheet metal ange (about 1” in height) that is hanging
down from the bottom of the truck bed oor. (See diagram and photos). A small notch
needs to be made in this ange on the passenger side of the truck. Locate the center

truck bed cross member. Measure over 2 1/2” from the front of the cross member
and make a mark. This will be the center point of the notch that is needed. Mark a
1” wide by 1/2” tall notch. Remove the metal of the marked area with sheet metal

shears. This will allow the front angle iron crossmember to be installed.
