~(22.9 lbs. 29X21X7)~ PWM Dual RAD Fan/Aluminum Shroud Assembly

This Derale Performance Powerpack combines high-performing shrouded powerpacks with an advanced fan controller for optimal engine temperature control. It features an aluminum shroud (25 5/8" W x 17 1/8" H x 4" D overall depth) with a natural finish, allowing for custom aesthetic modifications. The dual 12" high output electric fans are IP-68 certified waterproof/dustproof, delivering a total of 4000 CFM (2000 per fan) and designed for thick, tight fin radiator cores. The included digital PWM Fan Controller uses Pulse Width Modulation to continuously adjust fan speeds from 0-100%, maintaining desired engine operating temperature, reducing amperage spikes, and increasing component life. This unit is designed for primary cooling and puller (engine side) applications only, with adjustable mounting options.
