Flex-a-lite has been one of the leaders in cooling fan technology for both cars and trucks for decades. Flex-a-lite was the first company to offer electric engine fan back in 1978! A Flex-a-lite cooling fan could provide you with a more efficient engine without the power train experienced with old mechanical fans. They offer a variety of sizes and styles; pushes, pullers, single and dual-fans... you name it! Flex-a-lite also manufactures radiators, fluid coolers, and belt driven flex fans, which are all lighter and more efficient than OEM ones.
