GMC Sierra 3500 HD Radiator - Mishimoto - Aluminum, MMRAD-DMAX-11 - `11-`15 free shipping

GMC Sierra 3500 HD Radiator - Mishimoto - Aluminum, MMRAD-DMAX-11 - `11-`15. This direct-fit Mishimoto aluminum radiator is designed for 2011–2015 GMC Sierra 3500 HD applications with the 6.6L Duramax LML engine, offering improved cooling capacity in a factory-compatible package.

Built from aircraft-grade aluminum with a 100% brazed-aluminum core and polished end tanks, the MMRAD-DMAX-11 increases coolant capacity by approximately 22% and improves heat dissipation for towing, hauling, or performance driving. The TIG-welded construction and polished end tanks provide durable, corrosion-resistant operation in demanding conditions. The radiator retains factory mounting and hose locations, including a CNC-machined quick-disconnect outlet for direct connection to factory or Mishimoto silicone hose kits, so installation requires no cutting or modification.
