The factory upper and lower coolant hoses on the 2019+ Ram 1500 5.7L V8 are EPDM rubber, a material that hardens and loses flexibility as it cycles through years of heat. The Mishimoto Silicone Coolant Hose Kit replaces both hoses with silicone, built to handle higher heat and system pressure than the factory material allows. The upper hose is wire reinforced to help it hold its shape under heat and vibration, and the lower hose replaces the OEM's plastic joiner and multiple clamps connecting the main and auxiliary hybrid cooling lines with a single one-piece design, removing those failure points.----The kit includes the upper hose, lower hose, and worm gear clamps needed for installation, everything required is in the box. Install is plug-and-play, with no modification required. Available in black, red, or blue to match your engine bay. Confirmed direct fit for the 2019+ Ram 1500 5.7L V8. Backed by the Mishimoto Lifetime Warranty.
