Description
The Mishimoto Silicone Radiator Hose Kit (MMHOSE-RAM-91BK) replaces the aging rubber coolant hoses on first-generation 5.9L Cummins-powered Dodge trucks with a 4-ply silicone upper and lower hose set rated to withstand up to 330F. Built for owners keeping the legendary 6BT engine running strong after decades of service, this black hose kit pairs high-grade silicone construction with a full set of stainless-steel worm gear clamps for a straightforward cooling system upgrade over factory rubber.
As part of Mishimoto’s Cooling lineup, this hose kit is built from high-grade silicone reinforced with embedded heat-resistant fibers for a Performance-grade alternative to factory rubber hoses. Rated for a maximum temperature of 330F, it is a specific-fit item rather than a universal hose, and it includes stainless-steel worm gear clamps to support installation. Choosing this Mishimoto silicone radiator hose kit means added resistance to heat and degradation in the cooling system, engine bay style with the black silicone finish, and the backing of the Mishimoto Lifetime Warranty. This kit is intended for trucks equipped with a factory-installed intercooler system.
Vehicle Applications
This Mishimoto silicone radiator hose kit is a specific fit for 1991-1993 Dodge D250, D350, W250, and W350 trucks powered by the 5.9L Cummins I6 engine. Because fitment is specific rather than universal, confirm that your truck falls within this application range and is equipped with a factory-installed intercooler system before ordering.
