STEP EIGHT
Install the ½-inch x 8 ¼-inch U-bolt from inside the frame through the
holes in the sideplate above and below the frame, use a lock washer
and nut on each end of the U-bolt. Repeat this procedure on the passenger side of the truck with the other sideplate. (While installing
the U-bolts around the frame use caution not to damage or pinch the
wiring harness or brake lines).
WITH FACTORY INSTALLED BRAKE CONTROL
(if no factory install brake control is present continue to Step 8B)
Step 8A: To relocate the brake relay; rst insert a 3/4” X 2-1/2” bolt through the relay
bracket. (see Step 1) Next slide a frame bushing onto the bolt. (see Step 2) The hole in the frame is oval shaped. B&W
provides a frame bushing that converts the oval hole into a round hole. From the inside of the frame insert the bolt
with bracket and bushing into the frame and sideplate making certain that the frame bushing is in the oval hole in the
frame. Fasten the bracket with a 3/4” lock washer and nut on the outside of the side plate. (see Step 3) Next install
the brake control relay by sliding
its two bolts onto the relay bracket
and tighten. (see Step 4) Repeat the
bolting process on the passenger side
minus the relay bracket. Continue to
Step Nine.
WITHOUT FACTORY INSTALLED BRAKE CONTROL
(if the truck is equipped with a factory installed brake control see Step 8A)
Step 8B: Install the ¾-inch by 2 ½-inch bolt. Place a at washer and frame insert on the 3/4” bolt and install the
bolt from inside the frame through the lower rear hole in the side plate. Fasten with a lock washer and nut. (The hole
in the frame is a slotted hole, and B&W provides an insert that converts the slotted hole to a 3/4” round hole).
STEP NINE - TIGHTEN HARDWARE
When completed, tighten all the hardware in this order: Tighten the center section bolts to the cross members to
80 ft. lbs. and then make certain the hitch is square with the frame. Tighten the ¾” sideplate bolts to 120 ft lbs.
and then tighten the frame clamping U-bolts. Tighten the U-bolts slowly; alternating between the top and bottom
legs of the u-bolt until equally tightened to a maximum of 40 ft lbs. This torque may not be obtained without bending the sideplate some. This is normal and will not hinder the function of the hitch. Next tighten the three carriage
bolts on each sideplate to 60 ft. lbs and then tighten the sideplates to the front crossmembers to 80 ft. lbs.
STEP TEN – 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 ELEVEN - INSTALL SAFETY CHAIN U-BOLTS
To install the safety chain brackets (8) 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 brackets (8) 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 1/4” of thread extends
through the lock nut.
STEP TWELVE -REPLACE EXHAUST BRACKET
Reinstall the exhaust hanger brackets and the spare tire if removed during step 2.
STEP THIRTEEN - ENGAGE LATCH PIN
Retract the latch pin by pulling the handle all the way out until it stops and then rotating it clockwise. Place the 2-5/16”
Ball (10) in the hitch receiver. Engage the latch pin by rotating the handle counter clockwise. Be certain the latch pin
passes through the holes in the 2-5/16” Ball and fully engages through the hitch receiver. Finally, remove and lightly
grease the four corners on the square base of the 2-5/16” Ball.

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.
NOTICE
In some Truck models, plastic wheel well liners are present which extend past the side plate installation location on the
frame. A portion of the liner may need to be cut away over the area where the side plate will be installed.
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:
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, remove the lower exhaust bracket. Simply pull
the hanger rod out of the rubber bracket hole and 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 FLOOR
Begin by verifying and measuring the correct hole location in the truck bed oor. Measure from the back end (tail- gate
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 difcult 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 uses a 3/4”
piece of plywood as a
drilling guide to prevent the hole saw from
moving while drilling
the 4” hole in the truck
bed.

Short Bed 44 1/4 inches
Step 1:
Locate the fuel valve.
Step 2:
Disengage the locking pin.
Step 5: Replace fuel valve to bracket on fuel tank.
Step 3:
Slide fuel valve from bracket.
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 SIDEPLATES
Beginning in 2007 some models could be equipped with a factory installed trailer
brake system. In this case, a relay will have to be relocated before the driver’s side
sideplate can be installed. If the relay is present, there will be two bolt heads just
above the large oval hole in the frame on the driver’s side. Loosen these bolts and
slide relay to detach it from the frame.
Beginning in 2009 the models with factory installed trailer braking systems have a
wiring clip attached to the bottom of the frame on both sides of the truck just ahead
of the axle. This bracket must be removed and relocated as shown.
Step 4:
Install Turnoverball™ Center Section.
STEP FOUR - BED FLANGE MODIFICATION
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 sheers. This will allow the front angle iron crossmember to be installed.
STEP FIVE - CROSS MEMBER INSTALLATION
Place the 48” front cross member (1) between the truck frame and bed oor using
the notch made in step four. Be sure the holes in the cross member are facing
to the rear of the truck. Slide the cross member across both 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. Slide the
crossmember forward to the front edge of the 4” hole
in the bed. Next install the 46 1/2” rear cross member
bar (2) between the truck frame and bed oor. Rotate
the rear cross member a quarter turn so the threaded
holes are offset to the bottom of the bar and slide back
until there is enough room for the center section to be
placed between the two cross members.
Remove wiring clip
by pulling/prying
out of frame.
Next install the sideplates. The driver’s sideplate is shown, with the bent ange to the front, and the large holes to
the rear. Attach the two pieces of the sideplate together with ½” carriage bolts. The carriage bolts should be inserted
into the square holes from the backside of the sideplates and fastened using a at washer, lock washer and nut on
each bolt. This can be completed before installation on the frame rail. Do not tighten at this time. Attach the ange on
the sideplate to the front cross member using a ½ x 1 1/2 inch bolt, at washer, lock washer and nut. Insert the bolt
through the ange so that the nut when tightened is on the front side of the cross member. Next attach the rear bar
to the sideplate ear threading a ½ inch by 1 ½ inch bolt with at and lock washer into the bar.
Install side plate and insert
clip into slot provided.
Side plate installed
and clip in place.
