CSF Radiator 2-Row 42mm Aluminum Core with B-Tube Technology

CSF Radiator 2-Row 42mm Aluminum Core with B-Tube Technology Upgrade cooling performance and durability with the CSF 2-row radiator featuring a 42mm aluminum core and exclusive B-Tube Technology. Engineered for higher fluid capacity and superior heat dissipation, this radiator delivers reliable temperature control under heavy loads and extreme conditions. B-Tube Technology: Increases heat transfer by ~15% over standard oval welded tubes. 42mm 2-row aluminum core: Greater fluid capacity and improved cooling surface for faster heat rejection. Multi-louvered fins: Maximize airflow through the core for efficient thermal performance. Durable construction: High-grade aluminum end tanks TIG welded to the core for extra strength—no weak OEM plastic crimp points. Plug-and-play fit: True drop-in replacement requires no trimming or modification; includes pre-cut double-sided foam strips to seal the fan shroud for optimized airflow. Built-in transmission cooler: Heavy-duty 5-plate design connects to OEM hoses and helps manage transmission heat during towing, low-speed crawling, or with oversized tires. This CSF radiator is ideal for drivers who demand rugged reliability and improved cooling—especially when towing or running larger tires that increase drivetrain load and heat. Install quickly, drive confidently, and protect your engine and transmission with proven performance.
