Store / Cummins / 2007.5-2009 6.7L Cummins

The 2007.5-2009 6.7L Cummins, often referred to as the first-generation 6.7L, marked a significant shift in Cummins' design philosophy. Introduced mid-way through the 2007 model year to meet new, stricter EPA emissions standards, this engine was a major departure from the previous 5.9L and ushered in the era of "clean diesel" for Dodge Ram trucks.
