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. 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.
Features
- Constructed from four layers of silicone with heat-resistant embedded fibers
- Increased reliability compared to factory rubber hoses
- Improves heat and pressure tolerance
