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
Removing the spare tire will ease in the installation of the hitch. Refer to the owner’s
manual for the spare tire removal instructions. A section of the exhaust heat shield
will need to be removed. Locate the bed crossmember that is directly over the axle
and the next one forward (toward the front of the truck). The section of heat shield
between these two crossmembers will have to be removed. This can be removed by
cutting along the crossmembers with tin snips or an air chisel. Make sure that none
of the heat shield is protruding past the front of the bed crossmember that is directly
over the axle this could interfere with the rear hitch crossmember.
STEP TWO - REMOVE EXHAUST HANGER
To ease in the installation of the center section remove the tail pipe hanger from the
rubber mount. Simply pry the pin on the hanger out of the rubber mount. Once this is done a spacer can be placed
between the frame and tail pipe to add clearance between the tail pipe and the bottom of the truck bed.
STEP THREE - MARKING AND CUTTING 4 INCH HOLE IN TRUCK BED
Begin by measuring for the correct hole location in the truck bed oor. Measure from the tail gate end of the truck bed
oor by hooking a tape measure over the end of the truck box and mark the oor at the correct measurement (See below). Next nd the center point between the wheel wells, where these marks intersect with the rst measurement will
be the center point of your four inch hole. This Location is critical to the correct installation of the B & W Turnoverball™
so measure, mark and saw carefully. Make a four inch hole at this location. B & W recommends using a four inch hole
saw, however the hole can be cut by other means. If your truck has a spray-in bed liner you will need to take into account when you are measuring to add the thickness of the applied liner that has been sprayed over the end of the bed.
If your truck has a drop-in plastic bed liner, you may saw through both, but it is more difcult to accurately locate the
midpoint between the fender wheel wells, and to be sure that the bed liner does not move when sawing the hole. Once
you have the four inch hole in the bed use a deburring tool or a die grinder and carefully remove the burr from the under
side of the bed around the hole.
TIP: B & W uses a 2”x
8”x 30” board with a 4”
hole pre-drilled in it as
a drilling guide to prevent the hole saw from
moving while sawing the
four inch hole in the bed.
STEP FOUR - BED FLANGE MODIFICATION
The gap between the bed and frame is large enough to allow installation
of the crossmembers, but the gap is partially obstructed by a sheet metal
ange (about 1 inch in height) that is hanging down from the bottom of the
truck bed oor. (See diagram). A small notch needs to be made in this ange
on the Passenger’s side of the truck. Locate the truck bed cross member
over the axle in the wheel well on the passenger side of the truck. Measure
from the front of the cross member and make a mark at 6 ½”. This will be
the center point for the notch that is needed. Mark and cut a 1” wide by ½”
tall notch.
STEP FIVE - CROSSMEMBER INSTALLATION
Slide the angle iron cross member between the truck frame and the bed using the notch
that was made in step four. Be sure the holes in the cross member are facing the rear of
the truck. Once you start sliding the angle across the frame of the truck, we recommend
that you get under the truck and guide it across the frame rails taking care not to damage the brake lines along the driver side of the frame or fuel valve located on the back of
the fuel tank on some models. Once the crossmember is across the frame rails using the
rubber O-ring provided, secure a 1/2” 1-1/2” long bolt into the second hole in the cross
member from the drivers side. Next push the crossmember forward until the crossmember
is about four inches in front of the four inch hole in the truck
bed, making sure that the notch in the angle carefully goes
over the brake lines and wiring harness. Next install the cross
member bar between the truck frame and the bed. Start sliding
the bar across the frame then get under the truck to guide the
bar across the frame of the truck. Next rotate the bar a quarter
turn so the threaded holes are toward the bottom (an adjustable
wrench can aid in rotating the bar). Then slide the bar toward
the back of the truck until it is against the bed cross member.

APPLICATION UPDATE:
Beginning in 2004, a fuel valve mounted on the rear of the fuel tank on trucks equipped with gas engines, makes it more difcult to install the Turnoverball™ center section. This fuel valve can be easily removed and replaced to ease installation. Please
follow the following instructions:
Step 1:
Locate the fuel valve.
***HAND TIGHTEN ALL HARDWARE IN STEPS 6 THROUGH 9***
STEP SIX - CENTER SECTION INSTALLATION
Raise the center section into position between the crossmembers and carefully move it above the fuel tank from
beneath the truck. The receiver socket must be positioned
to the rear with the latch pin release arm on the driver’s
side. A lifting device, as described on Page 2 will help.
The round hitch receiver that protrudes from the top of
the center section must t through the hole in the truck
bed oor. Slide the front cross member back against
the center section so that the bolt installed previously
in the front cross member goes into the center section
hole directly across from it. Line up the rest of the holes and attach the two members with 1/2” x 1 1/2” long bolts,
lock washers, and nuts. Insert four 1/2” x 1 1/2” bolts, with at and lock washer installed, through the rear leg of the
center section into the threaded holes of the rear crossmember and hand tighten.
STEP SEVEN – INSTALL SIDEPLATE STUDS
Locate indicated hardware needed for this step and have it handy. Next, locate oval hole on the outside of the frame.
It is located about 4 inches behind the axle and measures roughly 1” x 1½”. To begin, place carriage bolt through hole
in locking strap. Next, hold the bolt and locking strap by only the bolt threads. Insert the long end of the locking strap
into the hole in the frame. Continue to move the locking strap into the frame until the head of the bolt passes into the
oval hole. Maneuver the bolt until the entire locking strap is inside the frame. Continue to hold onto the threads of
the bolt. With your free hand place
the frame bushing over the threads
and carefully move it into the oval in
the frame. This will insure that the
bolt is centered in the slot. Once you
are sure the frame bushing is inside
the oval hole and against the locking
strap, thread the retainer onto the
bolt threads. Tighten retainer so
bolt is held securely to the frame.
If necessary, a screwdriver may be
used in the small slot provided to
turn the retainer to make it tight.
Step 2:
Disengage the locking pin.
Step 5: Replace fuel valve to bracket on fuel tank.
Step 3:
Slide fuel valve from bracket.
Step 4:
Install Turnoverball™ Center Section.
STEP EIGHT - INSTALL SIDE PLATES
Next install the side plates. The driver’s side is shown; the longer ange goes toward the
front of the truck and the single oval hole to the rear. Place the side plate over the side
plate studs that have been installed in the frame. Secure with a at washer, lock washer,
and 1/2” nut. Hand tighten until the sideplate is against the frame and at washer on the
stud assembly. Attach the front ange of the side plate to the front angle crossmember.
Place a 1/2” by 1 1/2” bolt with a at washer though the ange and the front angle then
secure with a lock washer and nut. Next attach the sideplate to the rear bar by placing a
1/2” x1 1/2” bolt with a at washer, and lock washer though the smaller side plate ange
and threading it into the threaded hole in the bar.
STEP NINE - SIDE PLATE CLAMP & U-BOLT INSTALLATION
Install the sideplate clamp on the driver’s side. The sideplate clamp has two studs welded on the legs that will
pass though the highest and lowest hole in the side plate. There is a notch cut in the top inner part of the clamp
that will allow clearance for the brake lines on the top of the frame. The small hole in
the clamp should be toward the bottom. Slide the sideplate clamp between the wiring
harness and the inside of the frame making sure the top part of the clamp goes over
the brake lines. Push the clamp outward placing the studs through the holes in the side
plate. Be careful not to damage brake lines or wires. The sideplate clamp will set at a
diagonal when installed correctly. Place a 1/2” lock washer and nut on the studs. The
passenger side plate will use a U-bolt in the front two holes. The U-bolt will t around
the frame and will set vertically, not on a diagonal like the clamp. Place a lock washer
& nut on each of the threaded ends of the U-bolt once they have been installed through
the side plate holes.
STEP TEN – Tighten Hardware
It is very important to tighten hardware in the proper sequence. First check to insure that the hitch crossmembers are spaced about the same from side to side on the frame. Then tighten the center section bolts to 80 ft.
lbs. Next tighten the sideplate clamp and the u-bolt alternating slowly between the top and bottom legs so they
are equally tightened to 40 ft. lbs. tighten the bolts holding the side plates to the front and rear hitch crossmembers to 80 ft. lbs. then tighten the rear side plate studs to 80 ft. lbs.

STEP ELEVEN – INSTALL LATCH PIN RELEASE HANDLE
WARNING: LATCH PIN WILL NOT FUNCTION PROPERLY IF HANDLE IS NOT INSTALLED CORRECTLY.
Install the handle from underneath the truck by inserting it through the slot in the end of the center section
toward the driver’s side rear tire as shown. Attach the handle to the latch pin as shown with the handle on the
“cab side” of the square tab welded to the pin. The head of the bolt must be on the handle side, and the lock
nut must be on the tab side. The tab is welded to the pin in an offset position so that the handle will be lined
up over the center of the pin. If the handle is fastened to the other side of the tab, the handle will not function
properly. When installed
correctly the latch pin
may be disengaged
from the ball by pulling
on the handle from the
driver’s side wheel well
and rotating the handle
clockwise.
STEP TWELVE - INSTALL SAFETY CHAIN U-BOLTS
To install the safety chain U-bolts it is necessary to drill four 1/2” holes
through the truck bed oor. Drill the holes from beneath the truck,
through the two holes located on each side and closest to the round
receiver tube in the center section. This will locate the safety chain
U-bolt in the lowest point of the oor corrugation. Drop a U-bolt through
each pair of holes from the topside of the truck bed oor. Place a spring
and lock nut on each of the four legs. Tighten the lock nuts until ush
with the bottom of the U-bolts.
STEP THIRTEEN- REPLACE THE EXHAUST BRACKET
Re-attach the exhaust to the hanger bracket and replace spare tire if removed during the installation.

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.
