The Duramax is a General Motors diesel engine family for light- and medium duty trucks, designed by Isuzu. The 6.6-liter Duramax is produced by DMAX, a joint venture between GM and Isuzu in Moraine, Ohio. This engine was initially installed in 2001 model year Chevy and GMC trucks and has been an option since then in pickups, vans, and medium-duty trucks. In 2006, production at Moraine was reportedly limited to approximately 200,000 engines per year.[1] On May 9, 2007, DMAX announced the production of the 1,000,000th Duramax V-8 diesel at its Moraine facility.The HD variant is a heavy-duty light truck. It is a strengthened version of the Silverado/Sierra light-duty, and is available in the 1500HD, 2500HD, and 3500 models. The 1500HD, introduced in 2001, offers a Vortec 6000 V8 with 300 hp (224 kW) at 5200 rpm and 360 lb·ft (488 N·m) of torque at 4000 rpm with a Hydra-Matic 4L80E four-speed automatic transmission. The 2500HD also offers an available Duramax V8 with 300 hp (224 kW) at 3000 rpm and 550 lb·ft (746 N·m) of torque at 1600 rpm. Also available is the Vortec 8100 V8 with 340 hp (254 kW) at 4200 rpm and 455 lb·ft (617 N·m) of torque at 3200 rpm.

The 2500HD has an available five-speed (six-speed for 2006-2007 models) Allison 1000 transmission. The Silverado 3500 offers the same engine/transmission features that the 2500HD does, however it is usually equipped with "dually" twin wheels at the rear and has a stronger suspension. The HD models are primarily used for towing and high-weight cargo.

Towing capacity for the 1500HD is rated at 10,300 pounds (4,700 kg), and can haul 3,129 pounds (1,419 kg) in the bed. The 2500HD ups these ratings to 16,100 pounds (7,300 kg) with the 8.1 liter engine or 10,600 pounds (4,800 kg) with the 6.0 liter engine, and 4,058 pounds (1,841 kg), while the 3500 can tow 16,700 pounds (7,600 kg) and haul 5,511 pounds (2,500 kg). The addition of 4 wheel drive tends to reduce the towing and carrying capacity by 200 to 400 lb (181 kg), depending upon year and model. Other factors, such as options, can also affect these numbers.
