Mishimoto engineers know you love your Ram, which is why they've developed a new line of Dodge Ram peformance parts, including a direct-fit silicone boot kit with DuraCore™ technology designed specifically for the 6.7L Dodge Cummins. High-powered vehicles require high-performance products, which is why our Cummins performance boot kits are manufactured using DuraCore™ technology. Mishimoto DuraCore™ technology is the synthetic material that comprises the innermost layer of all Mishimoto silicone diesel boots. Compared to normal silicone, DuraCore™ provides superior resistance to heat, pressure, fuel, and oil. This effectively increases the life of our boots by preventing leaks and blowouts. To add even more reliability this Dodge Ram performance kit includes Mishimoto constant-tension T-bolt clamps for accurate and consistent holding power. The Mishimoto boot kit maintains factory fitment and, like all our Cummins performance parts, is protected by our signature Lifetime Warranty.
