6.7L CUMMINS SPECS, INFO, & RESOURCES

The 6.7L Cummins is the latest of the B-series engine family, introduced mid-model year in 2007. Replacement of the previous 5.9L ISB was necessitated as the result of stricter Federal emission standards and the need for a more competitive platform to permit future growth under growing industry constraints. It is the first Cummins to require a diesel particulate (DPF) system, which captures more than 90 percent of soot from the exhaust stream and cleans itself through a process known industry wide as “regeneration”. For the 2019 model year, the revised 6.7L Cummins set an industry record by reaching the 1,000 lb-ft benchmark in torque output.
