The 2008 Avalanche is available with the Z71 Off Road appearance package:
- Z71 Off Road suspension with high-pressure, gas-charged monotube shocks
- 18-inch on/off road tires
- automatic-locking differential
- front recovery hooks
- heavy skid plate
- high-capacity air cleaner
The Z71 package changes the Avalanche's appearance with large, color-keyed wheel flares and a bolder front fascia. You'll see more chrome, on the tubular assist steps, door handle centers, mirror caps and front grille inserts. Inside the Avalanche, a brushed metal appearance takes the place of woodgrain trim.
