GMC Sierra 2500 HD Radiator - Mishimoto - Aluminum, MMRAD-DMAX-11 - `11-`15 free shipping

GMC Sierra 2500 HD Radiator - Mishimoto - Aluminum, MMRAD-DMAX-11 - `11-`15. This direct-fit Mishimoto aluminum radiator is engineered for 2011–2015 6.6L Duramax LML-equipped Sierra/Silverado trucks and replaces the factory unit with a higher-capacity, all-aluminum assembly.

Built from aircraft-grade aluminum with a 100% brazed core and polished end tanks, this Mishimoto radiator increases coolant capacity and improves heat rejection while retaining factory mounting points and hose locations. The TIG-welded construction and CNC-machined outlet provide a durable, serviceable solution for enthusiasts who tow, haul, or push their trucks hard. It’s compatible with Mishimoto silicone coolant hoses and maintains OE fitment without cutting or trimming.
