1967 to 1972 GM Trucks - Dual 14 inch fan Shroud - For Entropy Engineering Radiators

Keep your GM or GMC Truck running cool with this precision-engineered fan shroud

Upgrade your cooling system with our custom-designed shroud for the 67 to 72 Entropy Engineering radiator with a core size of 28.25 x 17.438  See attached print to verify your radiator size.  Through optimized fan sizing and precision-engineered airflow channels, this shroud maximizes the contact between your fan and radiator surface—ensuring every CFM of airflow does its job.

Key Performance Advantages:

• Enhanced Shroud performance: Flap doors allow "pass through" of high velocity air while at speed, dramatically cutting down the need for fan usage.
• Optimized Fan Size: Direct fit 14" fans were selected by Monty
• Upper and Lower Mount Provision: Upper and lower flanges are recessed to allow removal of the shroud without removing the mounts.
• Not sure which fans to use? Check out Monty's independent fan CFM test results to see real-world performance data and compare different fan options.
• Better Fitment: Custom-contoured to the Entropy Engineering Radiator for a truly integrated cooling solution, overlapping the side tanks, accommodating larger fans, and providing provisions for your radiator brackets.
