Brand New Alumi-Tech aluminum shroud with dual SPAL Brushless 500 watt electric fans. These new SPAL 500 Watt brushless motors are the king of the cooling world. The benefits of these are that the cfm does not drop off while trying to pull through the stack (radiator, charge air cooler, a/c condenser, oil cooler). Included in this bolt in setup is the variable speed controller and all the wiring. With a variable speed controller the fans do not need to be pulling 100% if not needed. The speed ramps up or down with the temp of the engine.
The shroud is built out of 16 guage aluminum and TIG welded. The black flaps allow for natural airflow at highway speeds to eliminate cavitation.
Benefits:
Improved Fuel Milage
Increased Horse Power
Variable Speed Controlled
High Torque Motor (don't fall off with increased static pressure)
Built for the demands needed with towing
Tested on high horsepower/high boosted pulling trucks
