Give your Cummins an upgrade in reliability and style with the Mishimoto Silicone Coolant Hose Kit. Factory rubber radiator hoses are prone to degradation, causing leaks and blowouts. Whether your truck is stock or modified, the Mishimoto Silicone Coolant Hose Kit is a direct fit upgrade. This Cummins Silicone Coolant Hose Kit replaces the factory upper and lower Cummins radiator hoses with 100% silicone components. Mishimoto Cummins radiator hoses are constructed from high-grade 4-ply silicone with heat-resistant embedded fibers for superior heat and pressure tolerance. Silicone hoses are far more durable, reliable, and less prone to degradation than the factory rubber Cummins coolant hoses. Similar to the factory lower hose, the Mishimoto lower radiator hose utilizes an internal spring to prevent hose collapse. These Cummins coolant hoses are available in red, black, or blue and like all of our Cummins performance parts, includes our signature Mishimoto Lifetime Warranty.

Genuine Mishimoto. Part number MMHOSE-RAM-19BK.
