The combination of reliability, horsepower, and torque makes the Cummins inline six destined for hardworking trucks that have a good chassis and a subpar powerplant: Cummins swaps are popular. You’ve heard of FordCummins.com, right? A swap wasn’t necessary in this case, as the 24-valve Cummins was under the Dodge’s hood right from the beginning, and some key aftermarket upgrades made it that much better. Add-ons include an Edge Juice With Attitude programmer, a Smarty programmer, an aFe Bladerunner intake manifold, an AEM air filter system, a silicon hose kit from Mr. Bob’s, and an MBRP four-inch exhaust system. Street or dirt, this is one Dodge that’s hard to catch.
