The AFE 46-52031 BladeRunner Street Series Radiator offers more efficient heat transfer and better cooling than the stock radiator in your 2001-2005 GM 6.6L Duramax. This 4-row core radiator features a 2-3/4" thick tube and fin core that delivers maximum heat dissipation and enhanced coolant flow over the factory radiator for superior cooling efficiency. The fabricated end tanks are constructed out of 1/8" aircraft-grade aluminum plates for reliability and strength. With billet aluminum inlet and outlets for durability, these radiators are 100% TIG-welded for real-world proven longevity. A brass drain valve with fitting easily attaches to a hose for draining the antifreeze and the factory mounting position gives a stable, easy installation. The brushed aluminum finish and aFe POWER design painted on the front make this radiator unique as your truck.
