When it comes to towing a trailer, there are many factors to consider to ensure a safe and smooth ride. One important factor is trailer gain, also known as trailer brake gain or brake controller gain. Trailer gain refers to the amount of braking power that is applied to the trailer's brakes when the towing vehicle's brakes are applied. In this article, we will explore what trailer gain is, why it is important, and how to set it correctly for your trailer.
What is Trailer Gain?
In simple terms, trailer gain is the amount of braking force that is applied to the trailer's brakes when you press the brakes in your towing vehicle. The braking force is applied through the trailer's brake controller, which is typically installed in the towing vehicle's dash. The amount of braking force that is applied to the trailer is adjustable, which means you can set it according to the weight of your trailer and the type of driving conditions you expect to encounter.
Trailer gain is measured as a percentage of the maximum braking force that can be applied to the trailer's brakes. For example, if your trailer has a maximum braking force of 1,000 pounds and you set the trailer gain to 50%, then the brakes will apply 500 pounds of braking force when you press the brakes in your towing vehicle.
Why is Trailer Gain Important?
Trailer gain is important for several reasons. Firstly, it ensures that your trailer's brakes are working effectively and are able to slow down or stop the trailer when needed. This is particularly important when towing heavy trailers or when driving in hilly or mountainous terrain where you may need to brake frequently.
Secondly, setting the trailer gain correctly can help prevent trailer sway, which is when the trailer starts to sway from side to side behind the towing vehicle. This can be dangerous and can cause the trailer to jackknife or overturn. By applying the right amount of braking force to the trailer, you can help keep it stable and prevent sway from occurring.
How to Set Trailer Gain
Setting trailer gain correctly is essential for safe towing. The exact setting will depend on the weight of your trailer, the type of brakes it has, and the driving conditions you expect to encounter. In general, you should set the trailer gain to between 10% and 25% of the maximum braking force of the trailer.
To set the trailer gain, you will need to adjust the brake controller in your towing vehicle. This is typically done using a dial or button on the controller. Start by setting the gain to the lowest setting and then gradually increase it until you feel the trailer brakes engaging when you press the brakes in your towing vehicle. You should also test the trailer gain on a flat, level surface to ensure that it is working correctly.
Tips for Safe Towing
Aside from setting trailer gain correctly, there are several other tips that can help ensure safe towing. Firstly, make sure that your towing vehicle is rated to tow the weight of your trailer. Secondly, check that your trailer's brakes and lights are working correctly before setting off. Finally, always drive at a safe speed and maintain a safe distance from other vehicles on the road.
Conclusion
Trailer gain is an important factor to consider when towing a trailer. It ensures that your trailer's brakes are working effectively and can help prevent trailer sway. By setting the trailer gain correctly and following other safe towing tips, you can enjoy a safe and stress-free towing experience.
