Is the LBZ Duramax Still Worth Buying for a Used Diesel Truck?
The lbz duramax has a strong following in the diesel truck world because it blends useful power with a relatively simple heavy-duty design. General Motors used this version of the 6.6-liter Duramax in 2006 and into the 2007 Classic generation of Chevrolet Silverado HD and GMC Sierra HD pickups. In those trucks, GM rated the engine at 360 horsepower and 650 lb-ft of torque.
For today’s buyer, however, age matters just as much as engine design. A clean truck with good service records can be very different from one that has been heavily tuned, worked hard, or poorly maintained. Knowing the engine’s main features, driving traits, and common buying checks can help owners make a smarter decision.
