DeWitts Radiator Electric Fan Upgrade Kits
If you're running a single fan on your Corvette's stock radiator, then it's time to upgrade to DeWitt's aluminum electric dual Spal fan kits. These cooling systems are designed to move a massive amount of air when needed—the fan speed increases as temperatures rise. At the programmed upper threshold temperature, the primary fan speed reaches 100 percent and the secondary fan kicks in to help. As the temperature drops down, the secondary fan cycles off, and the primary slows, giving you a constant cooling temperature. You get uncompromised cooling under all driving conditions.

DeWitts Dual 11 in. Brushless Fan Kits
DeWitts dual 11 in. brushless fan kits were a result of a collaboration between DeWitts and Spal USA. Featuring a sleek, computer-designed ballistic injection molded shroud and two Spal Plus Series brushless fans, these systems move a combined 2,884 CFM, making them ideal for extreme performance demands and high-heat environments. They are direct-fit replacements for Spal dual brushed fan kits, sharing the same bolt pattern for quick and easy installation. Spal brushless fans were developed and designed with cutting-edge technology, high-energy ferrite magnets, and a state-of-the-art sine wave sensor-less drive. These motors reach more than 82 percent electrical efficiency, placing the 300-watt power range products among the most efficient motors anywhere. The result is high air-side performance at minimum electrical load. The brushless motor is fully sealed to be IP68 and IP6K9K compliant (water and dust proof) and can operate in the presence of many aggressive or hazardous substances. Each DeWitts kit includes everything needed: fan, harness, jumper, temperature sensor, and flaps. Additional features: * Quiet pulse-modulated variable speed operation * Fits any crossflow radiator with mounting tabs * Wiring requires no harness or computer modifications * Low amp draw soft start technology with 175 degrees on and variable to 205 degrees full speed
