While some owners never pushed their rigs hard enough to notice, those who did quickly found the factory system lacking. In addition, these trucks are getting to the age where radiators need to be replaced as a maintenance item. If you are going to be doing the labor, you might as well install the best possible radiator. Upgrading to the CSF Radiator offers: 60% larger core volume than the factory radiator. 100% TIG welded Aluminum construction (compared to plastic end tanks crimped). Core straps for strength and added rigidity for extreme reliability in demanding conditions. Ideal for turbo upgrades, high power/boost builds, towing, and off-roading.
