From Rainbow Products
The four most sought after fan/shroud combinations designed specifically for street rods and muscle cares alike. These fans offer a very sturdy "laser cut", one piece steel, powder coated bracket which allows not only free flowing, unrestricted circulation of air, but a hidden wire feature as well unlike ALL THREE of Rainbow Product's competitors. On all but one of our models we have added routed edging all the way around which affords a more bendable, molded look flowing into all edges of your radiator rather than just "cut straight" edging. All of these fan/shroud combinations are intended to be used as "pullers" only (to mount in BACK of your radiator). All of these fans are two-speed fans; at low speed they provide 2500 CFM and at high speed they provide 3200 CFM all are rated on a 12 volt system.
