Mishimoto is proud to expand their Cummins performance parts line to include the Mishimoto Dodge Ram radiator hoses for the 2003–2010 5.9L/6.7L Cummins are the perfect upgrade to the factory rubber Cummins coolant hoses. Mishimoto silicone Dodge Ram radiator hoses are crafted from a combination of high-grade silicone and four layers of heat-resistant fibers to provide improved heat reduction, superior durability, and increased pressure tolerance. Old degrading Cummins radiator hoses can cause potential engine damage when they fail; avoid this by upgrading to Mishimoto silicone Cummins radiator hoses. Mishimoto Cummins coolant hoses retain factory fitment and are available in black, blue, and red. As with all our Cummins performance parts, these Dodge Ram radiator hoses include the Mishimoto Lifetime Warranty.
