Step 4
Secure the passenger-side attachment by
fishwiring the 3/8" carriage bolts (#6) and
square hole spacers (#4) into each hole and
installing 3/8" flange nuts (#5) as shown.
Torque all hardware to 37 lb-ft.
Step 1
Begin by supporting the steering box and
idler arm, using a strap or jack stand.
Then, use a 16mm socket to remove the
three bolts passing through the frame
and into the steering box housing.
Step 2
Position the tow bar base plate (#1) on the
vehicle frame and secure it in place using the
previously removed bolts for the driver side
and a clamp on the passenger side.
Be sure to reattach the gear box on the
driver side as the bolts are installed.
Snug the hardware but do not fully tighten.
Step 3
Making sure the tow bar base plate (#1) is
level, drill four 13/32" holes in the vehicle
frame, using the passenger-side side plate
holes as a guide.

Towing Tips
Check your equipment Periodically check the condition of all towing equipment. Ensure all fasteners are tight and
that all structural components are sound. Do not tow with worn or damaged parts.
Vehicle manufacturer's recommendations Review the owner's manual for your towed vehicle and towing
vehicle for specific recommendations, capacities and requirements.
Installing the Permanent Base Plate Safety Cables
When dinghy towing a vehicle with a tow bar, base plate safety cables should be used at all times.
In the event of a disconnect, the safety cables are designed to help prevent complete vehicle separation.
When installing the safety cables, use the illustrations below as a guide.
Installation guidelines
1. The cables must be connected to
the base plate and the vehicle frame.
2. Two cables must be installed.
3. Each cable must meet or exceed the
gross weight of the towed vehicle.
4. Make sure cables do not pinch or interfere
with hoses, wiring or other components.
Note: Base plate safety cables are not a replacement for safety chains connecting the tow vehicle to the towed vehicle.
