2005 GMC Sierra 2500HD Overview

If you need to do some massive hauling, anywhere in the vicinity of 9000-12,000 pounds, the 2005 GMC Sierra 2500HD may be worth a look. The 3/4-ton pickup is equipped with part-time four-wheel drive and three engine choices, the most popular of which is the 6.6-liter turbodiesel Duramax V8 in combination with a 5-speed Allison automatic transmission. In 2005, this engine gets a horsepower boost to 310-hp and a torque boost to 605 lb-ft. Other engines are the standard 300-hp, 6.0-liter V8 and a 8.1-liter, 340-hp V8 with 455 lb-ft of torque. A 4-speed automatic, 5-speed manual, and 6-speed manual are transmission choices.

The 2005 Sierra 2500HD is available in either Work Truck, SLE, or SLT trims. The Work Truck comes as a Regular Cab, seating two or three in one row of seats, while the SLE and SLT are either Extended or Crew Cab, with two rows of seats for up to six people. The Regular Cab features an 8-foot pickup bed, while the Extended and Crew have a choice between a 6.5-foot or the 8-foot. Tie-downs are standard, and a bedliner and cargo cover are optional. Standard equipment on all trucks include air conditioning, cruise control, automatic headlights, 16-inch wheels, 4-wheel ABS brakes, and dual front airbags. Moving up through the trims adds power features, a CD player, leather seats, and a power driver's seat. The 4WD is helped by ten inches of ground clearance.

The biggest draw to the 2005 Sierra 2500HD is its towing capacity, and owners are pleased with its durability and muscle. When equipped with the Duramax and Allison combo, it can tow over 12,000 pounds. Owners also comment on the smooth ride, which doesn't feel like you're driving a 3/4-ton pickup, and the interior is roomy. Disappointments include the low-teens gas mileage, the interior layout, and reports of problems with the 4-speed automatic transmission.
