2006 GMC Sierra 1500HD SLT 4x4 Crew Cab 6.6 ft. box 153 in. WB

Overview

The GMC Sierra 1500 HD is the more powerfully equipped version of the Sierra 1500. Available only as a Crew Cab with a 6-foot-6-inch bed, the 1500HD hauls 3,073 pounds with two wheel drive, 2,766 pounds with four wheel drive, and tows 10,200 pounds. Power is provided by the same 6.0-liter V-8 that is available in the 2500HD and the 3500. Because of its short bed, the 1500HD rides more smoothly than the other heavy-duty trucks. Five-speed manual and four-speed automatic transmissions are offered. Standard features include ABS, air conditioning, cruise control, AM/FM/CD audio, an attractive chrome grille molding, a chrome rear step bumper, and 17-inch chromed steel wheels. Changes for 2006 are minimal.
