Mishimoto Silicone Coolant Hose Kit – 2019-2024 Ram 6.7L Cummins

Mishimoto MMHOSE-RAM-19BK black silicone coolant hose kit direct-fits 2019-2024 Ram 2500/3500/4500/5500 non-H.O. 6.7L Cummins. 4-ply, 330°F rated, lifetime warranty.

Description

The Mishimoto Silicone Coolant Hose Kit (MPN MMHOSE-RAM-19BK) is a black, direct-fit replacement for the factory upper and lower radiator hoses on non-H.O. 2019-2024 Ram 6.7L Cummins trucks. Built from 4-ply silicone with heat-resistant embedded fibers, this kit is engineered to outlast the OE rubber hoses it replaces while keeping your cooling system looking as tough as it runs.

Factory rubber radiator hoses on the Cummins-powered Ram lineup are prone to age-related degradation that can lead to leaks or sudden blowouts. Mishimoto’s Cooling lineup addresses that weak point with a silicone coolant hose kit that delivers improved heat and pressure tolerance compared to stock rubber. The lower hose retains an internal spring, just like the factory piece, to resist collapse under vacuum, while the included high-quality worm-gear clamps make installation straightforward on stock or modified trucks. Whether you’re refreshing an aging cooling system or upgrading a build, this kit is a durable, reliable option backed by the Mishimoto Lifetime Warranty.
