Key Features:
Engineered for durability and performance, the Mishimoto Silicone Hose Kit offers the following benefits:
- Constructed from high-grade 4-ply silicone with embedded heat-resistant fibers for exceptional thermal and pressure tolerance
- Includes both upper and lower main radiator hoses for a complete cooling system upgrade
- Internal spring reinforcement in the lower hose prevents collapse under vacuum conditions, maintaining consistent coolant flow
- Far more resistant to cracking, swelling, and degradation compared to factory rubber hoses
- Available in multiple colors including blue, black, and red to match your vehicle’s style

Construction & Design:
The Mishimoto Silicone Hose Kit is crafted from premium 4-ply silicone material reinforced with heat-resistant fibers, providing superior strength and flexibility. This construction allows the hoses to withstand extreme temperatures and high pressure environments typical of heavy-duty diesel engines. The lower radiator hose features an internal spring coil that prevents hose collapse during rapid coolant flow changes or vacuum conditions, a critical design element that mimics and improves upon the factory hose design.
Each hose is precision-molded to match the exact contours and dimensions of the 2015–2018 Ram 2500 and 3500 6.7L Cummins radiator connections, ensuring a secure, leak-free fit. The silicone material also resists oil, chemicals, and environmental contaminants better than traditional rubber, extending the service life of your cooling system components.
