Frequently asked questions

Do I need a brake controller to tow a trailer?

If your trailer has electric brakes and is over a certain weight, yes — a controller is needed for safe, balanced braking.

What's the difference between proportional and time-based controllers?

Proportional controllers match braking to how hard you stop for smoother control, while time-based ones apply a preset amount. A pro can recommend the right one.
