2008 GMC Sierra 2500HD SLT 4x2 Extended Cab 6.6 ft. box 143.5 in. WB

Overview

The GMC Sierra 2500HD is a full-size, heavy duty, three-quarter ton pickup truck that is nearly identical to the Chevy Silverado but features more mature, restrained styling. The bold Sierra 2500HD, like its Sierra and Silverado brethren, come with a dizzying array of options to choose from. Extensive combinations of cab size, cargo boxes and powertrains make this truck extremely customizable. Three available V-8 engines, including one turbocharged diesel version, are controlled by a six-speed automatic transmission. It can be equipped with an 8-foot cargo box. The Sierra 2500HD is available in regular, extended and crew cab body styles. Four-wheel antilock disc brakes are standard. The GMC Sierra 2500HD carries over from 2007 with little to no changes.
