2008 GMC SierraHD Crew Cab 6.6L V8 6AT (365 HP)

Vehicle Overview

GMC introduced a new generation of heavy-duty pickups in 2008, trying to keep its flag up despite the 2007 – 2009 world financial recession.

General Motors made the 3500HD lineup in a few body shapes, but some were addressed to the professionals. It was the heaviest truck before a CDL license was required and provided all the needs for a family. The Crew Cab version provided plenty of room on the rear seats to be used by a family of five going on a cross-country trip with a trailer in the back.

GM built the 3500HD version for work, and it showed it. Its front fascia was tall, fitted with big squared headlights and corner-mounted turn signals. Depending on the trim option, the front bumper was black, body-colored, or chromed. The Sierra 3500HD Crew Cab featured four regular-sized doors. Thanks to the side aluminum steps, it was easier for children to climb inside. GM built the four-door Sierra, with only one bed option, unlike its shorter-cabin brothers, which were available with a long or a short loading area.

Inside, GMC offered an option for a bench at the front, while most trim levels provided two buckets for the driver and side passenger and a bench for three in the back. The carmaker took its inspiration for the upper trim level (and some parts) from Cadillac and installed wood trims and powerful sound systems.

GMC claimed that the most demanded version was the diesel version with its 6.6-liter Duramax unit that came with enough torque to pull a house and, thanks to the engine braking system, it saved the brake pads. All engine versions sent their power to the rear or all four wheels. But that was mostly for the entire 3500HD range.
