Construction & Design

The hoses in this kit are crafted from premium silicone, a material known for its exceptional thermal stability and resistance to environmental stressors. Unlike traditional rubber hoses, silicone maintains its integrity under prolonged exposure to high temperatures and pressure fluctuations common in diesel engine cooling and transmission oil systems.

Each hose is reinforced internally to prevent collapse or deformation, ensuring consistent fluid flow and system performance. The included stainless steel clamps feature an embossed design that prevents cutting or abrasion of the silicone surface, enhancing the overall durability of the assembly.

Installation & Fitment

This hose kit is designed as a direct OEM replacement for Dodge Ram 2500 and 3500 models with the 5.9L diesel engine from 1994–1998 and 2003–2006. Installation requires no modifications, making it a straightforward upgrade for mechanics and DIY enthusiasts alike. Simply remove the old rubber hoses and clamps, then install the new silicone hoses with the supplied clamps for a secure, leak-free fit.

Its precise fitment ensures compatibility with existing heater and transmission oil cooler connections, preserving factory routing and minimizing installation time.
