US Motor Works 16934 High Output Dual 12-Inch Electric Radiator Fan and Shroud Kit 4000 CFM

The US Motor Works 16934 is a high-performance dual electric radiator fan and shroud kit engineered for serious primary cooling applications. This powerpack kit pairs two high output 265-watt Bosch motors with stator flow directors and an OE-quality injection molded fan shroud featuring pressure relief vents, delivering a combined 4,000 CFM of airflow to keep engine temperatures in check under demanding conditions.

Designed exclusively for puller (engine side) applications, this dual fan assembly replaces inefficient belt-driven fans, freeing up horsepower and improving fuel economy by eliminating unnecessary engine load. Each fan moves 2,000 CFM and draws 24.8 amps for a total draw of 49.6 amps, backed by an ultra-quiet, patented skewed-blade design that minimizes noise without sacrificing airflow performance.
