Upgrade Your Cooling System With Confidence

If you're looking to give your 2013-2014 RAM 2500 or 3500 with a 6.7L Cummins the kind of durability it deserves, the Mishimoto Silicone Radiator Hose Kit is a no-brainer. Whether your truck is bone stock or tuned to handle heavier loads and higher temperatures, these hoses provide the peace of mind that factory rubber just can't match. With the upper and lower hoses constructed from high-grade, four-ply silicone and reinforced with heat-resistant fibers, you get superior strength that holds up under pressure. This is especially important when your truck spends its life towing heavy or pushing hard through rough terrain. Mishimoto also included an internal spring in the lower hose to prevent collapse, ensuring consistent coolant flow even when things get hot. Available in sleek black, bright red, or bold blue, they look as good as they perform. And like all Mishimoto products, these hoses are backed by a lifetime warranty, so you can install them once and forget about them.

Engineered For Performance Under Extreme Heat

The Mishimoto MMHOSE-RAM-13BK Silicone Radiator Hose Kit was built with longevity and heat management in mind for the 2013-2014 6.7L Cummins platform. Each hose is crafted from four layers of premium silicone, reinforced with embedded heat-resistant fibers designed to handle elevated engine bay temperatures and sustained coolant pressure. This design drastically improves upon factory rubber hoses, which are prone to cracking, swelling, and heat fatigue over time. The lower hose features a pre-installed internal spring to protect against collapse under vacuum or high-rpm conditions, maintaining reliable coolant circulation. The silicone construction also allows for improved flexibility and tighter sealing, which minimizes the chances of leaks or failure during temperature swings. This kit is ideal for Cummins owners who demand more out of their cooling system, whether they’re running heavy-duty jobs, hauling up steep grades, or pushing additional horsepower. With OEM fitment and color options to match your style, it’s a practical upgrade with serious long-term benefits.
