GMC Trucks

GMC has been a mainstay in American automotive since 1911. Since that time, it has built a reputation for building trucks that are powerful and reliable. Many owners wouldn’t be able to do their jobs without them, but GMC trucks have also become extremely popular with people who don’t actually need them for work.

The GMC Sierra 2500 and Sierra 3500

The GMC Sierra 2500 and 3500 share automotive genetics with another very popular heavy-duty truck, the Chevrolet Silverado.

For the most part, GMC hasn’t altered the original model too much, though trim and add-on options have been varied a bit over the years. While the engines of early versions had substantial differences, that really hasn’t been the case in more than a decade.

The Duramax V8 Engine

Speaking of the engine, that’s one of the major selling points that have kept the GMC Sierra such a popular vehicle since the late 90s. Many owners opt for the Duramax V8 engine. This 6.6-liter diesel engine offers 8 variations:

  • LB7
  • LLY
  • LLY/LBZ
  • LMM
  • LGH
  • LML
  • L5P
  • LMK
