This kit is for: 2003-2004 GMC Sierra 2500 All

The CURT Assure brake control comes with a pressure-sensitive manual override button, a 1-1/2" wide OLED display and a triple-axis motion-sensing accelerometer, all to empower your adventure and provide smooth, responsive stops every time. The triple-axis accelerometer lays the foundation for this advanced electric brake controller, detecting the inertia of the vehicle and trailer on any grade. This means that whether you are going up or down a hill, the Assure is able to produce the exact amount of brake power needed, compensating for the angle and motion of the vehicle. The accelerometer also responsively adjusts this braking power as the vehicle slows down, putting the least amount of stress possible on your vehicle and trailer. The Assure trailer brake controller also features a high-quality OLED screen, displaying brake activity and providing an interface for the driver to control and monitor the trailer brakes. The display offers a clear picture with its 128 x 64 dot matrix screen, and the display can be tilted up for a clear visibility, whether the brake control is mounted above or below the dash. The manual override of the Assure allows brake pressure to be applied any time and in any amount. This can be used to help slow the vehicle down or correct trailer sway. The override button is pressure sensitive, giving you complete control over the trailer brake power. The CURT Assure can be used with two to eight trailer brakes, and it is compatible with ABS, cruise control, low-voltage systems and PWM systems. It has built-in reverse-polarity and short-circuit protectors, as well as low voltage and trailer disconnect indicators. Like all CURT brake controls, the Assure trailer brake controller installs using one of our vehicle-specific quick plug harnesses. It also comes with mounting hardware for a complete installation and is backed by a limited lifetime warranty.
