Ford Raptor High Performance Radiator - CSF - 2-Row, 42mm Aluminum Core, B-Tube Technology - 21-25. A direct-fit performance radiator engineered for 3rd Gen Raptors and 14th Gen F-150s, designed to reduce operating temperatures under heavy loads without requiring modifications.

This CSF radiator replaces the factory unit with a larger 2-row, 42mm aluminum core that increases coolant capacity and improves heat dissipation. CSF’s Exclusive B-Tube Technology boosts heat transfer by approximately 15% compared to standard oval-welded tubes, while new 5mm tall multi-louvered fins maximize surface area and airflow. Built with 100% TIG-welded aluminum end tanks and CNC-machined mounts, the unit is pressure and leak tested for long-term reliability. Ideal for towing, off-road use, and modified trucks where extra cooling margin is required.
