Chevrolet Silverado 2500 HD Radiator Coolant Hose Kit - Mishimoto - Silicone, 6.6L Duramax - Black - `11-`15. A direct-fit silicone hose kit designed for 2011–2015 Silverado 2500 HD trucks with the 6.6L Duramax, offering improved temperature and pressure resistance over stock rubber hoses.

This Mishimoto kit replaces the factory radiator hoses with high-grade silicone hoses reinforced by five layers of heat-resistant embedded fibers. It includes CNC-machined billet quick-disconnect ends for a factory-style connection with no cutting required, and T-bolt clamps for secure installation. The kit is compatible with both stock and modified cooling systems and is available in black to match OEM and aftermarket components. It also mates directly with Mishimoto 6.6L Duramax aluminum performance radiators.
