Our customers told us they would prefer a neutral color for the center instead of the red and blue that we have offered on our industry-leading Flex Fans. We listened, and took the product to the next level with a premium silver finish that looks like no other. We will also now use this premium finish on our Race Fans and OE Replacement Clutch Fans. This is a specially formulated silver coating that won't degrade or lose its luster in the harsh environment of an engine compartment. Best of all, the silver finish means it will look great under the hood, regardless of the color of the engine or engine compartment. The design of the fans and the material of the fan star and blades will remain the same. Flex-A-Lite Race Fans have a rigid blade design similar to an OE fan for maximum airflow. The advantage of the Race Fan is that they are designed for use without a fan clutch. This provides constant, reliable air flow from the cooling fan and eliminates the extra weight and length of the fan clutch.
