2006-2007 LLY / LBZ 6.6L Duramax Diesel Performance Products and Accessories

For 2006, GM upgraded the trucks computer system which made it possible to have more injections of fuel each combustion cycle, and  this is what distinguishes the 2006 LLY from its predecessor, the 2004.5-05 LLY.  This software upgrade was necessary in order to meet the emission standards for 2007.  With a class leading 360 horsepower and 650 foot pounds of torque these trucks are quite impressive!  The LBZ engines have many internal upgrades, such as a lower compression and a taller deck height, in order to handle increased boost levels, thus additional power, which is why  it is a great platform for building a performance monster!   

Products in this section are designed to work on 2006 and 2007 (classic body style) 6.6L GM Duramax equipped trucks unless otherwise noted.
