Integrated Trailer Brake Controller

With its impressive trailer-towing capacity, Suburban® is an awesome choice if you need a serious tow vehicle. Case in point: the Integrated Trailer Brake Controller (ITBC). The ITBC allows you to hook up the trailer's electric brakes to your vehicle, integrating them with the brake, antilock brake and StabiliTrak® systems. There's only one brake pedal – pressing down on your vehicle's brakes will activate your trailer brakes. When driving situations activate your vehicle's antilock system or the StabiliTrak electronic stability control system, the power sent to your trailer's brakes will be adjusted automatically to help minimize trailer wheel lockup.

The available power output to the trailer brakes can be modified to suit a variety of trailering situations via the trailer gain adjustment on the trailer brake control panel mounted on the instrument panel. To keep you informed of your ITBC settings, the Trailer Gain and Output can be viewed in the Driver Information Center display.

This feature is standard on 3/4 ton models. It requires the available Heavy-Duty Trailering Package on 1/2 ton models.
