Custom Aluminum Radiator Kit 19 x 31 Three Row

The Custom Aluminum Radiator Kit 19 x 31 Three Row by NORTHERN RADIATOR is designed for serious engine builders and performance enthusiasts who require enhanced cooling capacity without the added weight of traditional copper-brass units. This radiator is particularly suitable for high-output engines, turbocharged platforms, and vehicles operating in high-temperature environments.

Constructed from aluminum, this radiator offers nearly 50% weight savings compared to traditional designs while improving heat transfer efficiency through a well-optimized water jacket design and expanded fin density. The three-row core configuration increases surface area for superior convection, allowing for effective heat release, which is crucial for managing high horsepower outputs and sustained driving in extreme conditions.

Ideal for restomods, engine swaps, and compact performance builds, this radiator fits modern engine bay constraints while maintaining the cooling capacity of larger vintage designs. Mechanics and fabricators often specify this kit for engine builds that require a custom mounting solution with standard hose connections.
