2006 GMC Sierra 1500 SL2 4 Dr Crew Cab 5.8 ft. SB

The SL2 trim line for the 2006 GMC Sierra 1500 comes only in a four-door Crew Cab setup. This features four regular-size doors opening onto two rows of seats. Rear legroom increases to 39 inches instead of the 33 in the Extended models. The Crew Cab has the same wheelbase and overall length as the Extended, which means the extra interior room crops off some inches on the pickup bed, which is only 5.8 feet long. This half-ton, rear-wheel-drive pickup comes standard with a 285-hp, 4.8-liter V8 and 4-speed automatic. A 5-speed manual is optional, along with a 5.3-liter, 295-hp V8.

The 2006 GMC Sierra 1500 SL2 Crew Cab rides on 17-inch wheels with all-season tires and features 4-wheel ABS brakes, front disc and rear drum brakes, dual front airbags with passenger deactivation, and automatic headlights. A locking rear differential, traction control, and skid plates can be added. The pickup earns three and four stars in crash tests. The SL2 ups the ante of the SL1 with standard power windows, locks, and mirrors, heated mirrors, and remote entry. These join cruise control, a CD player, tilt and power steering, a front power outlet, intermittent wipers, and a tachometer. Both front and rear benches split-fold, and bucket seats are available for the front row, along with an overhead storage console and rear sliding window. Tow hooks are standard in the cargo bed, and a trailer hitch is optional. Towing capacity maxes out at 5,700 pounds. An extra option with the SL2 is satellite radio.
