Compatibility of Equalizer Weight Distribution on 2013 Dodge Ram 1500 with Built-In Sway Control

The built-in sway control systems offered in some late model vehicles use rear-mounted sensors to detect sway; they then automatically apply the brakes on the vehicle to compensate. Such systems are often better than no sway control, and may be fine for lighter trailer loads, but they may cause the vehicle brakes to wear out sooner than they would otherwise. Also, they do not provide any weight distribution function. Depending on the nature of the vehicle and trailer load, the weight distribution function may actually be more important than the sway control to maintaining stable overall handling.

My contact at Equalizer advises that a properly-rated and -installed Weight Distribution/Sway Control System should prevent the sway from reaching the point where the sensors trigger the vehicle brakes, so it may not be necessary to disable this system in the tow vehicle.

Your choice of Equalizer system must be based on an accurate measure of your trailer tongue weight in its typical fully-loaded as-towed state. If a system is rated too high, it will be too stiff and may cause erratic handling; if rated too low it could be ineffective or be damaged by the trailer load. You can use a tongue weight scale like the etrailer # e99044 or measure using one of the alternate methods outlined in the included article to determine your trailer tongue weight. I have also linked a general article on weight distribution systems that might be useful.

Once you know your trailer tongue weight you can use the link provided to select an appropriate system for your trailer. Some systems include the weight distribution shank; if your trailer requires a shank with a specific rise or drop you can choose a system and shank separately. You will also need to use an Equalizer hitch ball and these will be shown on the product page for the system.
