Mishimoto’s direct-fit silicone boot kit with DuraCore technology is made for 2017–2019 Chevy/GMC 6.6L L5P Duramax applications. DuraCore inner layers improve resistance to heat, fuel and oil compared with standard silicone, while stainless-steel reinforcing rings reduce expansion under high pressure. The kit includes constant-tension T-bolt clamps and fits using factory locations for a reliable seal and long service life.
