TRAILERING TECHNOLOGY

Sierra 2500HD puts trailer safety and control at your fingertips:

 

  • Available integrated trailer brake controller is located close to the steering wheel for easy adjustments and displays the level of brake force or “gain” in the Driver Information Center

BRAKING SYSTEMS

To let you engage an extra measure of braking confidence on long grades, or in Tow/Haul mode, Sierra 2500HD utilizes various technology to assure you stay at the desired speeds:

 

  • The available diesel exhaust brake uses engine compression to create “negative torque” to help slow the vehicle

  • Trailering hitch platform and 2.5” receiver with 2” adapter
