2008 GMC Sierra 3500HD SLE1 4x4 Regular Cab 8 ft. box 133 in. WB DRW

Overview

The GMC Sierra 3500HD is a full-size, heavy duty, 'one-ton' pickup truck twin to the Chevy Silverado but features more mature, restrained styling. A 353-hp 6.0L Vortec V-8 powers single rear-wheel (SRW) models, while dual rear-wheel (DRW) models have a 312-hp version of the 6.0L V-8. Both SRW and DRW versions are available with an optional 365-hp 6.6L Duramax diesel engine for extra towing capacity. Like all Sierras, the 3500HD is available in a wide array of bed sizes, wheelbases, drive types and cab sizes, as well as a variety of trim levels. Safety features include driver and passenger front air bags, tire pressure monitoring system (SRW only) and four-wheel antilock disc brakes. The Sierra 3500HD carries over from its redesign year (2007) with few changes.
