Mishimoto engineers know you love your Ram, which is why they've developed a new line of Dodge Ram performance 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, and that 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.
Mishimoto Automotive (“Mishimoto”) warrants its products under this lifetime limited warranty policy (“Warranty Policy”). This Warranty Policy applies solely to: (i) Mishimoto Products purchased directly from Mishimoto or Mishimoto authorized dealers (each a “Mishimoto Product” and collectively, the “Mishimoto Products”) and (ii) the original purchaser of such Mishimoto Product (“Purchaser”). This Warranty Policy is non-transferable and all claims under this Warranty Policy must be accompanied by the original sales receipt. The terms and conditions of this Warranty Policy are subject to change by Mishimoto at any time without notice.
