The aFe BladeRunner Street Series radiator upgrades the 2001-2005 Chevy Silverado and GMC Sierra 2500/3500 6.6L Duramax. Its oversized 2-3/4" thick tube-and-fin core adds 25% more coolant volume over the factory radiator for greater heat dissipation and flow, backed by 1/8" fabricated aluminum end tanks and billet aluminum inlet and outlet. The full TIG-welded build bolts to the factory mounting locations and includes a heavy-duty brass drain valve.
