CURT Electrical Trailer Brake Controllers
Simple installation. Sophisticated safety.
CURT offers several different trailer brake controller models to provide you with a solution that fits your unique towing setup and budget. We carry time-based and inertia-based or proportional brake controllers.
All CURT trailer brake controllers are designed for easy installation. Most use our quick plug harnesses, and each comes with its own set of features and benefits.
For a helpful guide in selecting a brake controller, see below.
Key features

Fast, easy installation
Easily calibrated for all towing needs
Time-based and proportional
Inertia-based vs. time-based
Two types of brake controllers:
CURT electric brake controllers fall into one of two categories: inertia-based or time-based. These refer to the method of activation used by the brake controller. Both types are safe and effective for stopping a trailer. However, depending on your needs, one may be preferred over the other.
Inertia-based
Inertia-based or proportional trailer brake controllers use an electronic mechanism, called an accelerometer, to detect the momentum of the vehicle-trailer combination while braking. The controller accentuates the trailer brakes in proportion to the momentum, allowing for a smooth, highly efficient stop.
Time-based
Time-based activation is less complex than inertia-based. When stopping, a time-based brake controller accentuates the trailer brakes based on whatever gain setting is input by the driver. Although simple in operation, time-based trailer brake controllers are effective and provide a more budget-friendly option.
How to select a trailer brake controller
Heavy-duty towing
If you are towing a heavy trailer or cargo, an inertia-based brake controller will provide superior control to make smoother stops and to put less strain on your vehicle.
Light-duty towing
If you’re towing a simple boat trailer or popup camper, a time-based trailer brake controller may be sufficient. CURT time-based controllers are easily adjustable for varying loads.
Frequent towing
If you’re planning to tow often, an inertia-based brake controller is recommended. The sophisticated operation will help prolong the life of your vehicle and trailer.
Occasional towing
If you only plan to tow a few times a year, such as for family camping trips during the summer, a time-based brake controller is an effective and budget-conscious option.
