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 @ firstname.lastname@example.org.
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.
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.
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.
