Control your trailer brakes while towing in your Sierra 1500 with this Proportional Brake Control and Adapter Harness from GMC Accessories. The TriFlex Proportional Brake Control tells the trailer brake system when to brake and how much pressure to apply with a digital display which shows power adjustments in 0.1 increments. This Sierra 1500 Proportional Trailer Brake Controlled maximizes the effectiveness of braking with nine levels of sensitivity adjustment for varying trailer loads or driving conditions. This trailer brake controller features a triple-axis, motion-sensing accelerometer to help with smooth, responsive stops. The third axis provides precise, dynamic brake power adjustment when going up or down an incline. The Brake Controller Package operates 2–8 brakes on 1–4 axles.
