The Cummins B-series engine has built a loyal fan base among Dodge truck owners since its introduction in the late 1980s, and for good reason. This workhorse engine family has provided reliable, strong performance for hundreds of thousands of customers, and millions of miles.
The engine has also proven to be exceptionally receptive to aftermarket upgrades, to the point where 500+ horsepower and 1,000+ lbs./ft. of torque are attainable with a few well-planned upgrades. Though not all Cummins owners are looking for this level of orbit-altering power and torque, it's nice to know it's possible. Here are a few of the latest goodies out for all versions of the Cummins 5.9, from the early 12-valves to the latest "600." And as soon as we know of stuff for the newest king of torque hill, the "610," we'll get those up as well.
