Gain Control And Sync Settings On Draw-Tite Brake Controller

Published 09/24/2014

Question:

I have a Ford F 150 pulling an Airstream trailer. What is a good Synch number for a fully loaded trailer? What is the appropriate Gain number for the loaded trailer? Your video was helpful, but it never said how to calculate the Gain or Synch numbers. Thanks for your help!

According to the instructions for the Draw-Tite Brake Controller, part # 5504, you will need to adjust the Sync and Gain controls when you have the trailer loaded. There is no scale available that tells you what the best number is for a particular weight as the road conditions and loads will vary.

The Sync Control adjusts the brake aggressiveness and should be changed to the driver preference.

The Gain Control should be set up during the initial setup and it controls the amount of power that is made available to the brakes when the pedal is pressed or if you use the manual control.
