A carry-over for 2005, the Sierra 1500HD is a full-size pick up with four doors and up-to-six-passenger seating featuring a 6.0Liter V8 that produces 300HP and 367LB-FT of torque. A heavy-duty four-speed hydra-matic transmission is standard with a tow/haul switch that lessens shifting when towing. The 1500HD Classic comes available in WT, SL and SLT trim levels with the option of four-wheel-drive.
