Thumbnail Filmstrip of 6.7 Cummins Bladerunner Street Series Radiator AFE 46-52201 Images
The AFE BladeRunner Street Series Radiator 46-52201 is a heavy-duty cooling powerhouse designed to replace the vulnerable, often corroded factory radiator in your Ram 2500/3500/4500/5500 6.7L Diesel. In the high-torque world of Cummins diesel engines, heat is the primary enemy of engine longevity. This radiator isn't just a replacement; it's a structural and thermal upgrade. By utilizing aircraft-grade aluminum and a significantly larger core, the BladeRunner ensures that even under heavy towing or high-ambient temperatures, your coolant stays within the optimal range. This prevents the heat soak that can lead to power loss and protects your engine’s vital internal components from thermal fatigue.
- Massive 2.2" 3-Row Core: Features a tube-and-fin core that is 31% larger than the factory unit, providing vastly superior heat dissipation and increased coolant capacity for optimum efficiency.
- Fabricated Aluminum End Tanks: Unlike plastic tanks that crack over time, these are constructed from 1/8" aircraft-grade aluminum plates for maximum strength and pressure resistance.
- 100% TIG-Welded: Every seam is hand-welded for proven durability, ensuring a leak-proof seal that can handle the vibrations and pressures of a heavy-duty diesel workhorse.
- Billet Aluminum Connections: The inlet and outlet are precision-machined from billet aluminum, eliminating the common failure points found in cast or plastic connectors.
- Service-Friendly Brass Drain Valve: Includes a heavy-duty brass petcock with an integrated hose fitting, making future coolant flushes clean and effortless.
- No-Modification Install: Engineered to utilize factory mounting locations, ensuring a stable, straightforward "drop-in" installation.
- Premium Brushed Finish: Features a sleek brushed aluminum look with the iconic aFe POWER logo, adding a custom, high-performance aesthetic to your engine bay.
From an educational perspective, the transition from a standard 2-row plastic-tank radiator to the AFE 3-row aluminum design is a significant leap in "heat rejection" capability. The increased surface area provided by the 2.2" thick core allows the air passing through the grille to strip away heat much more effectively than the thinner stock unit. Furthermore, the use of TIG-welded aluminum end tanks solves the most common cause of radiator failure: the degradation of the plastic-to-metal crimped seams. Whether you are hauling heavy loads across mountain passes or looking to bulletproof your daily driver, the BladeRunner Street Series provides the engineering for power, protection, and value that 6.7L Cummins owners demand.
