Towbars for Cars
Here at Pro Bars (2008) Ltd our trained towbar technicians ensure that all towbars meet our 16 point safety checklist. The current owners of the company focus on safety and customer satisfaction for all our clients.
We have over 100 towbar jigs on site, but can custom build towbars for all makes and models of vehicle.
The towbar installation process covers building the towbar, removing and refitting bumpers, wiring in
a 7-pin flat plug and the fitting and safety checking the towbars. This can be completed same day.
On the towbar we put a sticker with three ratings stated on it, the rating includes braked, unbraked and
tongue load. This is an indication on what rate your vehicle can tow. Refer to owners manual for the
manufacturers specifications. What the ratings mean, braked rating is the weight of the trailer you are
towing that has brakes on it (pulling strength), the unbraked rating is the weight of the trailer you are
towing without brakes on it (pulling strength), and the tongue load means the downward pressure on
the towbar(downward force). If you tow more than the recommended towing rate you are more likely
to have an accident and hurt or harm any person, also if you over tow you will not be able to claim
insurance and there will also be no third party insurance if you hit someone and damage their car. Also
extra canter-lever items in the towball e.g. bike racks and dog houses lessen the strength.
There are three different options for wiring depending on your vehicle. All options have a 7-pin flat
plug. There is the standard wiring for common cars. VTi wiring if you have LED tail lights, vehicle
computer controls, body control module, electronic control module, light control module. VMTi wiring
if you have earth side switching, e.g. Jaguar, Commodore, European car, 24 v – 12 v reducers e.g.
Nissan Safari, Motorhomes, American Stop/Indicator combined tail lights, compatible with trailers with
New Zealand does not have an official size towball. We install a 1 7/8” which is typical of New Zealand
built trailers, caravans and other general towed items. There is the option of a 50mm (2”) ball which
typically is use for commercial trailers and some caravans. There are other options of towballs such
as long shaft sizes available for people who have stabilizers.
Don’t think that cars are the only vehicles that we install towbars on. Pro Bars have install towbars on
tri-cycles, quad bikes and tractors.
All towbars tongues are at a standard height of 400mm from the ground. Tongues can be changed to
higher, lower or longer depending on your requirements.
