The Dexter Sway Control (DSC)

Dexter sway control unit

The DSC system is a critical safety item to stabilise the sway of a trailer or RV by continuously monitoring trailer yaw, side-to-side movement, left and right of the tow vehicle.

Some of the causes of sway are:

  • Poorly designed caravan.
  • Axle located too far forward.
  • Incorrect ball height.
  • Unsuitable tow-vehicle & caravan combination
  • Under inflated tyres
  • Incorrect weight distribution

How the Dexter Sway Control (DSC) works

The DSC continuously monitors trailer yaw, side-to-side movement, left and right of the tow vehicle.

A powerful, rapid processing capability captures the critical elements that affect sway conditions, then uses the information to sense how the sway will proceed without driver intervention.

The data collected in the event of sway is used to apply the brakes on the correct side of the trailer in a timely manner and with the proper braking level required based on sway conditions.

DSC works independently of the tow vehicle to dampen the trailer sway, quickly bringing the trailer under control.

The Dexter Sway Control comes with a 2 Year Limited Warranty. Check if your new caravan has DSC fitted or can be applied to your existing caravan.

As a rule sway control equipment should only be fitted to larger caravans that may occasionally be affected by strong gusty winds.

Before purchasing any sway control equipment, discuss your problems with people experienced in caravan towing. In some cases particular types of equipment may be unsuitable.

For example, some types are not recommended if override brakes are fitted.

Remember that even the best sway control equipment cannot be expected to, and should not, compensate for a towing vehicle that is too light, an unbalanced caravan or lack of a weight distribution hitch.
