Description
Part #: MMBK-DMAX-17
Mishimoto is proud to release a direct-fit silicone boot kit with DuraCore(TM) technology designed specifically for the 2017-2019 Chevrolet/GMC 6.6L L5P Duramax. Mishimoto DuraCore(TM) technology is a synthetic material that comprises the innermost layer of all Mishimoto silicone diesel boots. Compared to normal silicone, DuraCore(TM) 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, these couplers feature stainless-steel reinforcing rings to prevent expansion under high pressure that may result in a blowout and lost boost pressure. This kit also includes Mishimoto stainless-steel constant-tension T-bolt clamps for a reliable and consistent seal. As with all our products, this boot kit is protected by the Mishimoto Lifetime Warranty.
