2006 - 2007 6.6L DURAMAX LBZ
The GMC 6.6L Duramax LBZ, introduced in late 2005 for the 2006 model year, marked a significant leap in diesel engine performance. With 360 horsepower and 650 lb-ft of torque, the LBZ offered robust power and exceptional towing capabilities. Featuring stronger pistons, revised cylinder heads, and an advanced exhaust gas recirculation (EGR) system, the LBZ was designed for improved durability and emissions control. Though production ended in 2007, the LBZ remains highly regarded for its reliability, powerful performance, and strong aftermarket support, making it a favorite among diesel enthusiasts and truck owners.
