2004 What's New

The Chevrolet Avalanche saw only minor changes for the 2004 model year.  The standard shuffling of colors for the exterior occurred with Yellow and Signal Blue having a short one model year life.  The Bob Lutz effect continued to shape the Avalanche, as well as other GM products, with OnStar becoming a rather pricy stand alone option on all but Z-71 equipped models.  Side air bags also become a stand alone option.  The Avalanche had a number of small changes happen to its dimensions in 2004, growing a hair shorter and a hair taller from the 2003 model year.

Major changes from the 2003 model year include these standard features added:

  • Trailering Package becomes standard on 2500 series Avalanche*

  • 10 more horsepower to the 5.3 liter Vortec V-8 engine
