Key Benefits

Two-row, 2.21-inch thick brazed aluminum core provides ideal fluid temperatures for hauling, towing, and warm-climate driving — built for the thermal demands of the 6.6L Duramax.
CNC-machined quick-disconnect outlet mates perfectly with the stock hose connection, and the efficient core delivers superior heat dissipation over the factory unit.
Magnetic Drain Plug included — captures harmful metal debris with no additional hardware needed for a complete install.
Full aluminum design with TIG-welded construction replaces the aged, clogged, or leaking stock radiator that can no longer keep Duramax temps in check.
Two-row brazed aluminum core with 2.21-inch thickness efficiently moves heat into the airstream faster than the lower-volume OEM unit under sustained diesel loads.
Confirmed direct fit for 2006–2010 Chevrolet/GMC trucks equipped with the 6.6L Duramax — no cutting, fabricating, or adapter work required.
Oversized core handles the thermal demands of stock and modified Duramax builds, including performance-tuned and compound turbo setups running towing and hauling duty.
Own it for life — backed by Mishimoto's Lifetime Warranty, your investment is protected long after install day.
