Description Reviews Flex-A-Lite got its start with a unique belt driven fan that flexed at high engine RPM to reduce drag on the engine, and send more power to the wheels. They have applied that same engineering skill to develop a full line of cooling products designed to improve engine performance and efficiency, including radiators, electric fans, oil cooler systems, and even heaters. This universal fluid cooler mounting kit uses a push thru black nylon connector that you trim to fit. Use this kit to mount any Oil Cooler.
