Engine exhaust brake

  • Reduces the amount of conventional braking needed while towing a heavy trailer or driving downhill
  • Uses the variable vanes in the turbocharger to smoothly and quietly create additional back pressure in the engine to help slow the vehicle
  • Works with the transmission's Tow/Haul mode and Auto Grade Braking to help the driver maintain the desired speed even on long, steep downgrades
. *May require additional optional equipment.
