The 2013–2018 Ram 2500 and 3500 represent some of the most refined Cummins trucks ever built — with torque ratings that climbed as high as 900 lb-ft by the end of this generation. Whether you’re running a stock engine pulling a fifth wheel or a tuned build making serious power, the factory plastic-tank radiator was never designed with real headroom for the thermal load this engine can produce. This 4-row extruded aluminum radiator is engineered specifically for the 2013–2018 Ram 2500 and 3500 with the 6.7L Cummins. It drops directly into the factory mounting locations with no cutting, no drilling, and no fabrication required.
Fluidyne eliminates that failure point entirely with a fully extruded aluminum core — a single-piece design with no brazed tube-to-header joints anywhere in the core. Every tank, fitting, and seam is finished with premium TIG welds throughout.
The 4-row extruded core delivers more effective heat rejection than conventional 4 or even 5-row brazed-tube designs, because every tube is formed from solid aluminum rather than folded and joined sheet. The fin pitch is optimized for the Ram’s factory shroud and fan configuration.
