Chevrolet Avalanche II: How to Remove the Bumpers

Model Description

The Chevrolet Avalanche II is the second generation of a unique pickup truck with a transformable cab, produced from 2006 to 2013. The model combines the functionality of a truck with the comfort of an SUV while retaining its distinctive design. Unlike many classic pickups, the Avalanche offered flexible usability thanks to its patented Midgate system, which allowed the closed cab to be converted into an open cargo platform.

Production Years and Modifications

The second-generation Avalanche debuted in 2006 and was produced until 2013, when General Motors discontinued the model due to declining demand for large pickups. The vehicle was based on the GMT900 platform, which was also used in the Chevrolet Tahoe and Suburban.

Main modifications:

• LS – Base version with minimal equipment (usually lacking leather upholstery and advanced multimedia systems).
• LT – More comfortable trim with improved finishes and additional features.
• LTZ – Top-tier version with leather seats, heating, upgraded audio systems, and chrome exterior details.

In 2009, the model underwent a minor facelift: the grille, headlights, and bumpers were updated, and new color options were introduced.

Design and Technical Features

The Avalanche II retained the model’s key feature—the Midgate system, which allowed:

• Folding down the rear cab wall, increasing the cargo bed length from 1.5 to 2.4 meters.
• Removing the rear window (optional) for transporting long items.
• Using removable panels over the bed, turning the pickup into an SUV-like vehicle.

The payload capacity reached 630 kg, and the towing capacity was up to 4.5 tons (in the V8 version).

Engines:

• 5.3L V8 (LS4) – 320 HP, 454 N·m (until 2010 with Active Fuel Management, later replaced with a more efficient version).
• 6.0L V8 (L76) – 366 HP, 515 N·m (available in all-wheel-drive versions).

Transmission: 4- or 6-speed automatic (depending on the production year).

Note: Depending on the production year, mounting points may vary slightly.

How to Remove the Front Bumper

1. Open the hood.
2. Under the hood, unscrew the six bolts securing the grille and the upper part of the bumper.
3. In the wheel arches, unscrew two bolts each and remove three plastic clips per side that secure the fender liners (front part).
4. Disconnect the fog light wiring harnesses.
5. From underneath, unscrew one bolt on each side (fastened from the engine side) securing the bumper to the brackets.
6. Release the clips in the fenders (pull the corners outward).
7. With an assistant, carefully pull the bumper forward.

How to Remove the Rear Bumper

1. (If present) Unscrew the bolts securing the trailer hitch to the rear bumper reinforcement.
2. Get under the vehicle.
3. Disconnect the electrical wiring harnesses.
4. Unscrew the bolts (or nuts) securing the reinforcement brackets to the frame.
5. With an assistant, carefully pull the bumper backward.

Why Was the Avalanche Discontinued?

Despite its innovation, by the 2010s, demand for large pickups declined due to rising fuel prices and the popularity of more compact models. In 2013, GM announced the discontinuation of the Avalanche, focusing instead on the Tahoe and Silverado.

Interesting Facts

• Military Version – In 2007, Chevrolet presented the Avalanche Extreme concept for the U.S. Army, but the project did not progress.
• Special Editions – In 2011, a limited-run Black Diamond Edition with exclusive trim was released.
• Film Appearances – The Avalanche II can be seen in Transformers: Revenge of the Fallen (2009) and the TV series Supernatural.
• Hybrid Version – A hybrid variant was tested in 2008 but never entered production.

Conclusion

The Chevrolet Avalanche II remains in history as one of the most unusual pickups, offering unique versatility. Although production ended over a decade ago, used models are still valued for their reliability and originality.
