Duramax Diesel Engines Comparisons and Specifications

When you choose Silverado HD, you can expect legendary capability. In fact, make that legendary dependability and durability too. Because when your truck comes from the family of the most dependable, longest-lasting full-size pickups on the road†, you can bet it works as hard as you do. - Chevrolet
The Duramax V8 engine is a General Motors Diesel V8 engine family for trucks. The 6.6-liter Duramax is produced by DMAX, a joint venture between GM and Isuzu in Moraine, Ohio. The Duramax block and heads are poured at The Defiance GM Powertrain foundry in Defiance County, Ohio. This engine was initially installed in 2001 Chevrolet and GMC trucks, and has been an option since then in pickups, vans, and medium-duty trucks.

​In the chart below, you will find the basic specifications and data for the Duramax engines used in Chevy trucks from the year 2001 to the current year. Although there were only 7 different types of base Duramax engines used in Chevys over the years, many of the separate listings take account for the different optimizations that General Motors and Chevy did to increase both the durability, power, and torque of these engines. For more specific information on these engines and a list of the trucks they were paired with, click on the name of the engine on the left side of the table. Since the different Duramax engines possess the same cylinder arrangement (V8) displacement (6.6L) and the same amount of valves (32 Valve), each engine in the chart will be referred to by their names (i.e. LB7, LLY, etc.)
