The NORTHERN RADIATOR Dual 12in Fans with Shroud (model Z40006) is a high-capacity electric cooling fan assembly engineered for vehicles requiring serious heat rejection. This dual-fan setup delivers exceptional airflow through a dedicated aluminum shroud, making it the choice for custom builds, high-performance applications, and off-road vehicles where factory cooling falls short. The curved blade design optimizes static pressure and efficiency across a range of engine temperatures.
At 21 x 4.5 x 29 inches and weighing 9.23 lbs, this assembly strikes a balance between substantial cooling capacity and practical installation in engine bays with moderate clearance. The dual 12-inch fan configuration distributes airflow across a larger surface area than single-fan designs, reducing strain on each motor while maintaining superior heat dissipation. The natural aluminum construction resists corrosion and integrates seamlessly with radiator cores in both street and trail environments. The integrated shroud design concentrates cooling air through the radiator matrix rather than allowing hot air recirculation—a critical detail for vehicles running continuously in high-load conditions or desert climates.
This cooling fan assembly suits builders and owners of vintage hot rods, custom trucks, off-road expedition vehicles, and performance machines where modern OEM cooling systems are unavailable or undersized. It's particularly valuable for vehicles operating in high-ambient environments, towing heavy loads, or climbing steep grades where sustained high engine temperatures degrade oil viscosity and accelerate wear. The NORTHERN RADIATOR brand has established itself as a reliable source for cooling system components where failure is not an option.
Installation and wiring specifications depend on your vehicle's electrical system and radiator configuration. Verify shroud clearance against hood, fan blade-to-radiator spacing, and 12V or 24V supply requirements before ordering. TacticalSurplusUSA stocks this assembly for immediate shipment to builders and shops across North America.
