Mishimoto has released a direct-fit silicone hot-side boot kit with DuraCore technology designed specifically for the 6.6L LML Duramax. High-powered vehicles require high-performance products, which is why our 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 kit includes Mishimoto constant-tension T-bolt clamps for accurate and consistent holding power. The Mishimoto boot kit maintains factory fitment and is protected by our signature lifetime warranty. Features & Benefits Five layers of 100-percent silicone for maximum durability and blowout prevention Includes high-quality constant-tension T-bolt clamps Mishimoto Lifetime Warranty
