Flex-A-Lite Extruded Core Universal Radiator 28 x 20 LS Engine with Electric Fan


Flex-A-Lite Extruded Core Universal Radiator 28 x 20 LS Engine with Electric Fan

Flex-A-Lite Extruded Core Technology is the future of performance aluminum radiators, replacing multi-core radiators with a new advanced design. Flex-A-Lite Extruded Core Radiators provide significantly better cooling with a stronger, more durable and lighter design.

This dual-pass universal radiator designed for LS engine swaps. The radiator measures 28 inches wide and 20 inches tall and comes with a fully-shrouded Black Magic Xtreme S-Blade electric fan mounted. The fan moves 3,300 cfm of airflow and includes an Adjustable Thermostatic Controller, making this a complete unit, ready to install. This radiator and electric-fan module can be used in a variety of performance vehicles, including racing, street cars, trucks and off-road. Adjustable 90-degree side brackets facilitate a variety of mounting possibilities. Side tanks included welded captured nuts to make mounting electric fans easy. Radiator includes 22-24 lbs. cap and train petcock.

Features and Benefits:

  • Increases contact area between coolant and the aluminum tubes for better heat rejection and cooling
  • Provides a flat surface to braze the cooling fins to, maximizing the contact between the tubes and fins for increased heat rejection and better cooling
  • Cooling fins have been designed with louver patterns cut into them to direct airflow, improving heat rejection and cooling
  • Wind tunnel testing has shown that this Extruded Tube Core technology is significantly more efficient for cooling than standard tube radiators
  • The Flex-A-Lite Extruded Tube Core Radiators are significantly stronger and have a 100-psi burst rating
  • Flex-A-Lite Extruded Tube Core Radiators include a corner subhead, reinforcing the cooling tube to header connection; an area prone to cracking and leaking in other brands of aluminum radiators
  • Covered by an exclusive Flex-A-Lite transferable 2-year warranty
