Extruded Core Radiator and Dual Electric Fans 73-87 Full Size 1/2-ton GM Truck and SUV LS Engine Flex-A-Lite

Flex-A-Lite Extruded Core Radiator and Dual Electric Fans 1973-1987 Full Size 1/2-ton GM Truck and SUV LS Engine

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 direct-fit radiator is engineered to bolt into a 1973-1987 full-size 1/2-ton Chevrolet or GMC truck or SUV with an LS engine swap. No cutting or drilling is required for installation, and the radiator will mount using the factory location and equipment. Includes a fully-shrouded dual-fan system that moves 4,600 cfm of airflow and a Variable Speed Controller. 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
