Selling my 2006 GMC Sierra 3500 SLE Dually 4x4, equipped with the highly sought-after 6.6L LBZ Duramax Turbo Diesel V8 and Allison 1000 6-speed automatic transmission.
This truck has just 74,000 original miles and comes with a clean title in my name.
The 2006–2007 Classic LBZ Duramax is widely considered one of the most desirable generations of GM diesel trucks, known for its reliability, towing capability, and pre-DPF emissions design.
Finding a low-mileage LBZ is becoming increasingly difficult, especially in a 3500 Dually 4x4 configuration.

Why This Truck Is Special
The LBZ Duramax is one of the most respected diesel engines GM ever produced, delivering 360 horsepower and 650 lb-ft of torque from the factory.
Paired with the Allison 6-speed automatic, this drivetrain is known for its durability and excellent towing performance.
Unlike newer diesel trucks, the LBZ was produced before factory diesel particulate filters (DPF) became standard.
With only 74,000 original miles, a clean title, and several desirable upgrades, this Sierra is an excellent choice for diesel enthusiasts, collectors, or anyone looking for a capable heavy-duty truck.
