How to adjust the height of a tow bar?

The ability to adjust the height of a tow bar is required by many types of users, who may need to lower or raise it as required. This is not just a requirement for off-road enthusiasts driving iconic vehicles such as the Land Rover Defender, Mitsubishi Pajero, Nissan Patrol or Hummer. In fact, adjustable tow bars have a wide range of applications and are used by drivers of all types of vehicle.

They are particularly useful for trailer users transporting materials, equipment or vehicles. Users include outdoor adventure enthusiasts as well as drivers of lorries, vans, motorhomes, military vehicles and agricultural tractors.

The challenge of towball height: a common problem for heavy trailers

Many drivers face the necessity of adjusting the height of the tow ball. Legislation prescribes a standard height of between 35 and 42 cm from the ground, so it is often necessary to adjust the position of the tow ball to ensure greater stability and safety.

This is most often necessary when heavy trailers are being used.

When a trailer is loaded and the towing vehicle is unloaded, the trailer may tip over, with the rear tending to sag. This phenomenon compromises stability while driving and can have negative consequences.

• Transport safety: the risk of losing control of the trailer increases.
• Wear and tear to components such as tyres and shock absorbers, which may malfunction.

Adjusting the height of the tow ball is a frequently discussed topic. Here are some of the most frequently asked questions:

• What is the correct height for a tow ball?
• How do I balance a trailer?
• What should I do if the trailer hangs down during towing?

Towing height adjustment solutions

Adjusting the height of the tow ball is essential to ensure that the trailer is balanced and level when towing, improving stability and safety. There are several practical solutions that allow these adjustments to be made without having to replace the entire hitch or modify the vehicle chassis.

Here are some of the most common options:

• Height-adjustable side plates for the hitch;
• Adjustable plates for the tow ball;
• Air suspension on the rear axle.

Towing ball height adjustment plates

Adjustment plates are a simple and inexpensive way to change the height of the towball, adapting it to different towing requirements. While many systems are available on the market, it is important to note that most are not approved for road use.
