Ford F-150 High Performance Radiator - CSF - 2-Row, 42mm Aluminum Core, B-Tube Technology - `21-`25. A direct-fit, high-capacity radiator engineered for '21–'25 F-150 and Raptor models to reduce coolant temperatures and improve cooling reliability under heavy loads.

This CSF radiator uses a 2-row, 42mm aluminum core and exclusive B-Tube technology to increase heat transfer compared to standard oval-welded tubes. The ultra-efficient multi-louvered fins and new 5mm tall fin design boost surface area contact and airflow, helping reduce engine temperature during towing, off-road use, and spirited driving. Constructed with 100% TIG-welded aluminum end tanks and CNC-machined mounting points, the unit is built for durability and repeatable performance. It is a true drop-in fit with OEM-style inlet/outlet and is individually leak- and pressure-tested before shipment.

Features

• 2-Row, 42mm high-capacity aluminum core
• CSF B-Tube Technology — ~15% increased heat transfer over oval tubes
• New 5mm multi-louvered fins for improved airflow and heat dissipation
• 100% TIG-welded aluminum construction with CNC mounting hardware

This radiator provides a significant upgrade in cooling volume and efficiency—useful for daily drivers who tow, owners adding modifications, and enthusiasts pushing their trucks harder than stock. It helps maintain optimal coolant temperatures, reduces the risk of heat-related power loss, and replaces plastic end-tank designs with all-aluminum construction for improved longevity.
