6.6L DURAMAX LLY

DURAMAX LLY SPECS & INFO

The LLY is indicative of the Duramax’s towards meeting strict emissions requirements in the U.S. while keeping the engine competitive in the market. The 2004 LLY was the first Duramax to utilize exhaust gas recirculation (EGR) and a variable vane turbocharger (VVT). The Garrett VVT provided noticeably favorable performance characteristics in comparison to the LB7’s IHI fixed geometry turbo. For the 2006 model year, the LLY underwent minor changes, yielding an 85 lb-ft improvement over the 2004/2005 model. These changes are perceived to have been made in preparation to meet future emissions requirements as well as increase torque output to maintain a competitive edge. 2006 would make the last year for the LLY, but the next generation would build upon the changes made to the Duramax platform. The Duramax LLY phased out the LB7 during the 2004 model year and continued production until 2006. For the 2007 model year, the next generation LBZ would take over entirely. LLY’s were available in Chevrolet Silverado HD, GMC Sierra HD, Hummer H1, Chevrolet Kodiak, and GMC TopKick models (the Kodiak and TopKick being medium duty trucks in GM’s lineup). The LLY was the first emissions controlled Duramax and available mated to the Allison 1000 automatic (5 speed for 2004/2005 model years, 6 speed for 2006 model year) or the ZF 6 speed manual transmission.
