The Mishimoto MMBK-DMAX-11HBK Factory-Fit Boot Kit for your 2011-2016 GM 6.6L Duramax LML is a direct-fit silicone hot-side boot kit with built-in 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 the signature Mishimoto Lifetime Warranty.
