Fan Electric 15in DualSh rouded Puller Controls

The FLEX-A-LITE Fan Electric 15in Dual Shrouded Puller Controls (Part No. 104641) is a direct-fit dual 15-inch electric cooling fan assembly designed specifically for Dodge Ram fullsize trucks and Cummins diesel engines from 2003 to 2009. This puller-style fan system delivers 5500 CFM of airflow at 12V, engineered to manage the elevated cooling demands of diesel powerplants and heavy-duty towing applications where factory cooling capacity falls short.

The dual 15-inch curved blade configuration maximizes cooling efficiency while the aluminum shroud minimizes parasitic drag and weight compared to traditional mechanical fans. The integrated electronic controller provides automatic temperature-based engagement, meaning the fan runs only when needed—reducing parasitic load on the engine during highway cruising and improving fuel economy. The kit arrives complete with all necessary mounting hardware and control electronics, eliminating the need for supplemental wiring or fabrication work.

This cooling system is essential for owners running heavier loads, towing, or living in hot climates where stock cooling struggles to maintain safe engine temperatures under sustained load. Dodge Cummins owners performing engine modifications, turbo upgrades, or increased boost also benefit from the additional cooling capacity. The 5500 CFM specification provides margin above factory demand, preventing thermal cycling and extending engine life—particularly critical for diesel engines where temperature consistency directly affects injection timing and longevity.

Direct-fit electric fans have become the standard upgrade path for second-generation Cummins trucks, offering reliability and simplicity over aftermarket mechanical clutch conversions. The fan's puller design (drawing air through the radiator rather than pushing) provides more efficient heat exchange and better clearance around engine bay components.
