CSF Radiator 2-Row 42mm Aluminum Core with B-Tube Technology Upgrade cooling performance and durability with the CSF 2-Row 42mm aluminum core radiator featuring exclusive B-Tube Technology . This high-capacity unit is engineered to reduce engine and transmission temperatures under demanding conditions — towing, off-road crawling, and vehicles running oversized tires. Improved heat dissipation: 42mm dual-row aluminum core increases fluid capacity and cooling surface. B-Tube Technology: Boosts heat transfer by ~15% compared to standard oval-welded tubes. Multi-louvered fins: Super-efficient fins maximize airflow through the core for optimum thermal management. All-aluminum construction: High-grade aluminum end tanks TIG-welded to the core for superior strength vs. OEM plastic/crimp designs. Built-in transmission oil cooler: Heavy-duty 5-plate design connects to OEM hoses to control transmission temps under load. Plug-and-play fit: True drop-in replacement with no trimming or modifications required; includes pre-cut double-sided foam strips to seal the fan shroud and improve airflow efficiency. This radiator is ideal for drivers who demand reliability and temperature control when towing, rock crawling, or running larger tires that increase drivetrain load and heat.
