    Flex-a-fit Radiators have internal fins that act as heat sinks to absorb heat faster from the engine coolant to then radiate it via external fins. This increases the tank's radiant surface area threefold. Unique external fins integrate convenient fastening points into the tank itself, transforming the radiator into a bracket to attach electric fans, expansion tanks, oil coolers, etc. The sidetank design simplifies an otherwise tough radiator swap using only a few drilled brackets. Flex-a-lite Radiators are all aluminum with 2-row core 1"/26mm tubes, various core sizes, and left or right inlets. Radiator mounting brackets included; cooler and accessory brackets sold separately. Some radiators are available with fans.

    Flex-a-fit Aluminum Radiators are:
  • 41% more efficient than brass radiator tanks
  • 104% more efficient than composite radiator tanks
  • 135% more efficient than aluminum aftermarket radiator tanks
