Description

The LB7 Duramax was first launched in 2001, when GM’s 6.5L Detroit diesel was phased out. The Duramax outperformed the obsolete Detroit and marked a watershed moment in the diesel industry for Chevrolet and GMC pickups. Since it predates emissions standards, the engine is unlike any other Duramax unit. As a result, it’s known for its dependability and is thought to be an especially cost-effective variant of the engine.

The GMC Sierra HD, Chevrolet Silverado HD, GMC TopKick (medium duty), and Chevrolet Kodiak all use the LB7 (medium duty). The LB7 had problems with fuel injectors, as impressive as GM’s new engine platform appeared to be. Due to the high frequency of injector failures, GM was forced to recall these units and replace them with a new design. In addition, the warranty was expanded to cover the new injectors for up to 200k miles to give existing customers peace of mind.
