Description
Cummins 2.5" blue silicone cabin lower heater hose for '03-'07, 5.9L Dodge Ram trucks.When replacing the upper heater hose we recommend inspecting your factory clamps before ordering. Sometimes these clamps are re-usable but if they are rusty, we recommend replacing the clamps with the factory spring clamp 3930310 or a suitable worm gear clamp.
