Smarter Power for the 5.9L That Works as Hard as You Do

If your 2000–2002 Dodge Ram 5.9L Cummins is more than just a weekend toy—if it’s your daily driver, your work rig, or the truck that never says no—then the DFC Diesel SS590002SOALB Street Series Speed of Air Long Block was built with you in mind. This isn’t just a reman engine—it’s a fully re-engineered powerplant designed to deliver more drivability, lower maintenance, and increased reliability. At its core is DFC’s precision-machined long block, assembled with all new OEM or better components, including Total Seal® gapless rings, upgraded gaskets, and a professionally remanufactured cylinder head. What makes this build really stand out is the Speed of Air™ Hyperformance pistons. Featuring aerospace-grade coatings and CNC-machined “turbulators,” these pistons boost combustion efficiency, reduce EGTs by up to 200°, and help lower fuel consumption while delivering more torque where you actually use it—down low in the RPM range.

Built for Real-World Performance and Longevity

The Street Series isn’t for someone looking to gamble on budget parts or questionable cores—it’s for truck owners who want lasting value. Every detail is built around long-term durability, from the ARP Series 2000 or OptiTorque head studs (depending on availability) to the Cometic MLS head gasket and precisely honed block bored for the next oversized piston. The smoother combustion process enabled by the Speed of Air pistons means less soot, less wear, and cleaner oil between intervals, which translates into fewer service visits and better long-term performance. With reduced visible exhaust, quieter operation, and noticeable drivability improvements reported after just a few hundred miles, this engine doesn’t just replace what was lost—it enhances every part of your truck’s performance. And with a 5-year, 100,000-mile warranty, DFC backs it all with the kind of confidence only possible when every detail has been dialed in.
