New Hampshire's Original Diesel Performance and Repair Specialists



2004.5-2006 LLY

The 2nd generation Duramax was made available halfway through the 2004 model year.  This new model shared most parts other than the drivetrain and electronics with its LB7 predecessor but this new engine addressed many known issues with the LB7. This was also the first Duramax to have a VGT Turbo.
