Heavy-Duty Trailering Package

Avalanche® does look like fun, but it's built for hard work, too. It offers plenty of hauling power, and the addition of the Heavy-Duty Trailering Package provides even more trailering capabilities – more than enough for towing big items such as a boat. The Heavy-Duty Trailering Package includes the following:

  • 3.42 rear axle ratio
  • External transmission oil cooler
  • Engine oil cooler

It also includes a 2-speed active transfer case on 4WD models.

On LS and LT models, requires the available Texas Edition and All-Star Edition.
