    Mishimoto's direct-fit silicone hot-side boot kit with DuraCore technology designed specifically for the 6.6L LML Duramax. High-powered Duramax trucks require Duramax performance parts, 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 your 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 like all of their Duramax performance parts, is protected by the signature Mishimoto Lifetime Warranty.

    Features:
  • Note: This boot kit fits hot-side (driver side) only
  • Direct fit for the 2011+ Chevrolet/GMC 6.6L Duramax
