Truck Towbar Hitches

Truck towbars and hitches provide the connection point between a truck and compatible trailer or towing equipment. Unlike choosing a towbar based on vehicle fitment alone, truck towing setups also need to account for the vehicle and trailer combination, required coupling, towbar rating, chassis compatibility and applicable towing requirements.

Truck towbar designs can vary considerably between applications. Some are intended for lighter truck applications, while others are designed around the requirements of heavier rigid trucks. The correct solution depends on the truck, its chassis and the towing task rather than simply selecting the highest-rated towbar available.

What Is a Truck Towbar Hitch?

A truck towbar is a structural towing component fitted to the rear of a truck to provide a secure mounting point for compatible towing hardware. The hitch or coupling arrangement then provides the connection between the truck and trailer.

Depending on the setup, the towbar may accommodate different coupling arrangements rather than having a single permanently fixed tow ball. This can be useful in commercial applications where the truck may need to connect to different compatible trailers.

The towbar, coupling and mounting system need to work together as a complete towing arrangement. The rating or capability of one component does not automatically determine the allowable towing capacity of the complete vehicle and trailer combination.

Types of Truck Towbars

Truck towbars are available in different configurations to suit different chassis layouts, truck sizes and towing requirements.

Towbar systems may be intended for light, medium or heavier rigid truck applications, with different designs and ratings according to their intended use. Some are designed for a specific vehicle or chassis application, while universal or multi-fit truck towbars can accommodate a range of compatible installations when correctly configured.

A universal-fit design should not be interpreted as fitting every truck. Chassis dimensions, mounting requirements, towbar specifications and the intended towing application still need to be checked.

Centre-Mount Bar Hitches

A centre-mount bar hitch positions the primary hitch or coupling mounting point around the centre of the towbar assembly.

Depending on the towbar design, the centre mounting arrangement may allow compatible coupling hardware to be fitted or changed according to the towing application.

Check the individual towbar specifications to determine the supported coupling arrangement, receiver or mounting dimensions and applicable ratings.

Under-Mount Bar Hitches

An under-mount bar hitch positions the towing connection according to an under-mount arrangement suited to the particular towbar and chassis installation.

Available space, chassis configuration and the required towing connection can all influence whether this type of arrangement is suitable.

As with other truck towbars, the individual product specifications and installation requirements should be checked rather than assuming that an under-mount design is interchangeable between truck applications.

With or Without End Plates

Truck towbar designs can also differ in the way the bar is configured for attachment to the vehicle chassis. Some systems incorporate end plates or related mounting components, while others may use a different installation arrangement.

Whether end plates are required depends on the towbar design and truck application. Mounting components should therefore be selected according to the specific towbar and installation requirements rather than treated as universal towing hardware.

Coupling Options for Truck Towbars

One advantage of some truck towbar and hitch systems is the ability to use different compatible coupling arrangements.

Depending on the towbar design, removable or interchangeable mounting arrangements may allow the towing connection to be configured for different coupling types. This does not mean every coupling can be fitted to every towbar. Mounting pattern, dimensions, ratings and compatibility all need to be confirmed.

50mm and 70mm Tow Balls

Tow balls provide a familiar coupling point for trailers equipped with a compatible ball coupling.

Common sizes include 50mm and 70mm tow balls. The tow ball size must match the trailer coupling, while the tow ball, mount and associated towing equipment must also have appropriate ratings for the application.

A larger tow ball should not automatically be interpreted as increasing the truck's towing capacity. The allowable towing limits depend on the complete vehicle, towbar, coupling and trailer combination.

Pintle Hooks and Pintle Mounts

Pintle hooks provide another type of towing connection used with compatible trailer coupling hardware. A pintle mount provides the appropriate mounting arrangement for the hook where supported by the towbar system.

Where a truck needs to work with different trailers, an interchangeable hitch arrangement may make it possible to change between compatible coupling types. Any change still needs to remain within the specifications of the towbar, mounting system and towing combination.

What to Check Before Buying a Truck Towbar

Choosing a truck towbar involves more than matching a product to a vehicle description. The truck, towbar, coupling and trailer need to be considered together.

Start by checking the vehicle manufacturer's towing limits and the specifications applicable to the towbar and coupling. Relevant considerations can include:

• The truck and chassis configuration
• The intended trailer and towing application
• Towbar and coupling ratings
• Required coupling type
• Receiver or mounting dimensions
• Aggregate Trailer Mass (ATM)
• Gross Trailer Mass (GTM)
• Applicable static vertical or tow ball load
• Compatibility between the towbar, hitch and trailer coupling
• Any additional equipment required for the towing setup

The maximum permissible figure is not determined by whichever component has the highest rating. Vehicle, towbar, coupling, trailer and regulatory limits all need to be considered, with the applicable limit governing the setup.

If you're uncertain about compatibility or ratings, confirm the requirements before purchasing or installing the towbar.

Compliance and Installation Requirements

Truck towbar installation needs to account for both the product requirements and the regulations applicable to the vehicle and towing setup.

In Australia, towing connections and their installation can be subject to Australian Design Rule requirements, including ADR 62, which covers mechanical connections between vehicles. The requirements that apply depend on the vehicle, component and installation.

Rather than assuming every truck towbar carries the same certification or approval, check the documentation supplied for the individual product and its intended application. Relevant identification, rating and compliance information should be confirmed before use.

Installation requirements also vary. Depending on the truck and towbar design, fitting may involve mounting to the chassis and potentially additional fabrication or modification specified by the product or installation instructions.

For this reason, truck towbar installation should be completed by an appropriately qualified or experienced professional in accordance with the product requirements and applicable regulations.

Wiring and Accessories for Truck Towbars

The physical towbar is only one part of many truck towing setups. The trailer may also require electrical connections and other towing equipment appropriate to its configuration.

Trailer wiring provides the electrical connection required for functions such as trailer lighting. Depending on the truck and trailer, the towing setup may also involve equipment such as an electric brake controller or a breakaway system.

These systems perform different functions and their requirements depend on the vehicle, trailer and applicable regulations. They should therefore be selected and installed according to the complete towing combination rather than assumed to be included with the towbar.

Other towing accessories can include compatible tow balls, pintle equipment, plugs, sockets, adapters, locks and related towing hardware. Explore Fulcrum's Tow Bar Accessories range for additional components required to complete your towing setup.

Find Truck Towbars and Hitches for Your Vehicle

Correct truck towbar fitment depends on the vehicle, chassis configuration, towing requirements and coupling setup.
