History of the LBZ

Around a decade ago, Chevrolet began offering the LB7 engine in a variety of its vehicles. From 2001 through mid-2004, the engine was dependable, and it was well received. However, in mid-2004, Chevy released the LLY engine, which despite being popular at the time had several performance issues including overheating. To address these difficulties as well as other issues, Chevrolet replaced the LLY with the Duramax LBZ in 2006.

What Made the LBZ Special?

The LBZ was the first Duramax engine to be paired with the six-speed Allison 1000 automatic gearbox. The new six-speed transmission could handle greater power than the previous five-speed.

The LBZ, which was the first diesel engine from General Motors to feature direct injection, was also one of the last Duramax engines produced without emissions control technology. Because of this, despite being over a decade out of production, Chevy Silverado and GMC Sierra HD trucks with the LBZ engine are still in high demand.

The LBZ Duramax engine is not limited by emissions control technology, which helps to explain why it performs and lasts so much longer than the LLY. In addition to the engine not being restricted by emissions control technology, improved LBZ Duramax components contributed to its performance and durability. A stronger block allowed for more horsepower and torque vs. the LLY (LDV).

The LBZ has been improved over the LLY by adding:

  • In the LBZ’s main bearing regions, there is more webbing.
  • Main bearing cap heights are reduced.
  • For the main cap bolts, 4mm deeper bores were added.

To allow for the larger bolt holes, the oil feed ports were made 2 millimeters smaller.

The LBZ engine also used stronger rods. The steel-forged and cracked-cap design of the LLY and LB7 rods may have been identical, but they were beefier on the large end than the other two engines. This implies that they could handle approximately 100 more horsepower than the previous engines in terms of performance. More rotating mass was brought about by the meatier rods, although it was uncommon for a LBZ engine to have bent rods.

The larger 8-cylinder engine was both more powerful and more fuel-efficient. It also got a mild facelift in the form of new and improved fuel rails and injectors. The extra pressure was created by the Bosch CP3 fuel pump.

The LBZ has a larger turbo inlet manifold, as opposed to the LLY. This revision removed an earlier limitation on the compressor side of the turbocharger, resulting in cooler intake and exhaust temperatures. The greater amount of power sent through the engine also reduced lag by allowing it to work less hard.
