DSC vs ESC – Dexter Sway Control vs AL-KO Electronic Stability Contol

As certified installers for both Dexter Sway Control and AL-KO Electronic Sway Control systems we can offer you unbiased advice on choosing the best system for your rig.
Our top recommendations for increasing your caravan towing safety on the road.          

If you have towed a caravan before, you are probably familiar with the unnerving experience of encountering caravan sway. Caravan sway, commonly referred to as “yaw” or “fishtailing”, can range from a brief and frightening experience through to a complete loss of vehicle control resulting in an accident. Swerving, side winds and air pressure changes caused by passing trucks are causes of caravan sway. Fortunately two sway control systems are available to be installed on your caravan to increase your towing safety. The Dexter Sway Control (DSC) and AL-KO Electronic Stability Control (ALKO-ESC) systems both work to detect and control the side to side movement of a caravan in relation to the tow vehicle.

In an emergency both DSC and AL-KO ESC will engage to control sway and save you from a potential accident however there are a few key differences in the systems and the way they operate. DSC applies the left and right brakes separately similar to ABS in a vehicle for quick sway correction. The sway control braking level is automatically varied, based on the severity of the sway. DSC is more sensitive to sway than the AL-KO ESC and will engage when smaller amounts of sway are detected. AL-KO ESC applies a measured amount of braking based on the preset weight of the van and applies brakes on all wheels after significant sway force is detected.  DSC adjusts the braking for any caravan weight where AL-KO ESC is customized to each caravan with the unit programmed to the weight of the caravan specifically. This factor makes DSC more suitable when empty and loaded tow weights vary as with plant trailers and horse floats.  DSC is powered from the caravan battery and avoids the requirement for the system to be wired to the vehicle which is the case for AL-KO ESC.

If you take your van off-road you may be more inclined towards DSC as it features automatic off-road detection where AL-KO ESC needs to be unplugged from the vehicle. For AL-KO ESC a switch can be additionally installed in your vehicle to enable you to manually disengage/re-engage the system when off-road.

We have compiled a brief comparison of DSC vs Al-KO ESC that may guide you in your decision.
