This is one of our latest grinds for the Cummins 5.9L B series engine. After a lot of research developing these new profiles, we have dyno'ed around 50 different combinations of durations, lobe separation and installed centerlines to come up with the ultimate cam for the Cummins 5.9L 

This series 3 cam has gained a lot of popularity because of its strong mid range torque and horsepower in the mid range, but still has great bottom end drive-ability. Mods aren't required, but we do recommend a set of performance springs for this cam. You can expect to see a 2-3 MPG increase on average, and a decrease in smoke as well, around 30%
