Description
The Mishimoto Performance Fan Shroud Kit (MMFS-CK-78) is an aluminum fan shroud engineered exclusively for Mishimoto’s Chevrolet/GM C/K Performance Radiator, replacing the factory mechanical fan with two high-flow 14-inch electric fans that each move over 1300 cfm of air. Finished in silver aluminum with black plastic straight blades, this shroud arrives with the electric fans already attached and includes all mounting hardware needed for installation, with no cutting or bending required.
This Mishimoto cooling upgrade is built to eliminate the stock, failure-prone mechanical fan found on classic GM trucks, giving owners a plug-in electric fan setup instead. Because the fans are plug-in rather than hardwired, wiring is more straightforward, though the manufacturer notes that fans may require additional wiring to complete the installation. Shoppers can optionally pair this fan shroud kit with the Mishimoto Adjustable Fan Controller Kit for total control over coolant temperatures at idle. Like every Mishimoto cooling product, this fan shroud kit is backed by the Mishimoto Lifetime Warranty.
