Q. I have bought a vehicle with a Tow-Trust towbar and the towball is missing?

Fixed Towbars:

It is policy not to supply fixed towballs. A fixed towball should never be removed, if it is missing the risk of it having been done so due to impact/accident is too great on a safety critical major component, we recommend replacing the entire towbar for safety.

Detachable Towbars:

In theory it is possible to replace a missing detachable towball system if it has been lost, but due to towbars being safety critical items we ask that you contact your local towbar centre to carry out a safety & maintenance inspection to confirm the safety of your towbar (Safety & Maintenance Check).

If they are satisfied that the towbar is safe to use they will be able to fit a new detachable system, If any damage is found, or anything that leaves a question of doubt to the safety of the towbar, they will also be able to quote you for a full replacement towbar.

The towball is too low. What are my options?

It is often the case that one customer's height requirement is different to another depending on what make of trailer or caravan is being towed.  In many instances once a customer doesn't achieve the height they require, it is immediately assumed that it is the towbar that is the problem.  It is possible however that there are reasons for a low towing height that are not a towbar related issue.  Possible reasons include worn suspension that has lowered with time and modified sports suspension that sits lower than standard. You can check your towbar height via loading your vehicle to its laden position, however if you are still unsure please call your local Tow-Trust dealer or alternatively feel free to contact us direct @

What does laden mean when measuring the towball height?

M1 passenger vehicles under 3.5T can be ballasted to either vehicle GVW (Gross Vehicle Weight), or have 68kg placed on each outboard seating position of each row, and 7kg per occupied outboard placed in the luggage area. The other option for M1 passenger vehicles, and for all N1 category vehicles is to ballast the vehicle to GVW, while respecting the maximum axle masses as marked on the vehicle VIN plate.

What height will my towball be?

E.C. directive 94/20 states that the towball has to finish between the heights of 350mm and 420mm when the vehicle is laden, unless the vehicle manufacturer states otherwise.

I have an Alko hitch on my caravan, do I need a swan neck towbar?

An Alko 'aks' hitch is a trailer/caravan hitch that has friction 'pads' which grip the towball to help reduce sway.  If you have this type of hitch you either need to use a flange towbar with an Alko type towball or either a fixed or detachable swan neck towbar. The paint must be removed from the towball surface prior to towing.
