Fluidyne High Performance Extruded Tube Radiator 19-24 Ram 6.7L Cummins

If you tow heavy, spend time in hot climates, or simply rely on your truck every day, you already know how hard the cooling system works on a Ram 2500 or 3500 6.7L Cummins. Factory radiators can struggle under long pulls, added power, and constant heat cycling, especially on High Output trucks. This Fluidyne High Performance Extruded Tube Radiator is designed to give your truck a stronger, more durable cooling solution that helps maintain stable coolant temperatures when the workload gets serious. Unlike many factory and aftermarket radiators that use thinner, folded, and brazed tube construction, Fluidyne uses an extruded aluminum tube core made from a single piece of aluminum. This eliminates one of the most common failure points found in traditional radiator designs while improving overall strength and heat transfer. Combined with a proprietary fin design, thick tanks, and one of the densest cooling cores in the industry, this radiator is built to handle heavy towing, commercial hauling, hot weather, tuned applications, long mountain grades, and high-boost performance setups without the constant worry of cracked tanks or cooling system fatigue. Built specifically for Ram 2500 and 3500 trucks equipped with the 6.7L Cummins, including both Standard Output and High Output engines with either the 68RFE or Aisin AS69RC transmission, this radiator is engineered for direct compatibility with your truck’s factory cooling setup. The same extruded tube technology used in Fluidyne’s NASCAR oil coolers brings race-proven durability to real-world diesel use, giving Cummins owners a long-term cooling upgrade designed for reliability, performance, and confidence under load.
