Introduction
Dexter is proud to put control and peace of mind in hauling a trailer or
caravan back into your hands with the Dexter Sway Control System. This
innovative device automatically stabilizes the sway of a trailer. It works
independently of the tow vehicle and automatically applies the trailer or
caravan brakes in the event of a sway.
As you are driving, the Dexter Sway Control System is constantly
monitoring trailer yaw, or side-to-side movement, quickly recognizing and
adjusting for sway conditions.
This manual is designed to provide information for you to understand, use,
and guide you through the process of installing, operating, and maintaining
your Dexter Sway Control System.

as plastic covers or plastic walls. The center of the DSC (marked
by a red dot on the DSC label shown below) must be positioned
on the “center line” of the trailer and the DSC must be mounted
with the correct side in the UP direction as indicated on the label.
The longest edge of the DSC (as indicated by a red line on the
label) must be mounted parallel to the trailer axle beam(s). See
