Construction & Design

The hoses in this kit are crafted from reinforced silicone, a material known for its superior heat resistance and flexibility compared to traditional rubber. This construction allows the hoses to endure the high temperatures generated by powerful Hemi and SRT8 engines without degrading or losing shape. The silicone is reinforced with multiple fabric layers to enhance strength and prevent expansion under pressure, ensuring consistent coolant flow and system integrity.

Each hose is molded with exact bends and curves to match the original equipment specifications, providing a seamless fit that simplifies installation and maintains the vehicle’s factory routing. The included stainless steel clamps are embossed and non-perforated, designed to firmly secure the hoses without damaging the silicone surface, extending the lifespan of the entire assembly.

Installation & Fitment

This kit is a direct replacement for the factory heater coolant hoses on the following vehicles: 2005–2008 Dodge Magnum, 2005–2010 Chrysler 300, 2006–2010 Dodge Charger, and 2008–2010 Dodge Challenger equipped with 5.7L Hemi or 6.1L SRT8 engines. Installation requires no modifications, as the hoses are engineered to match OEM dimensions and routing precisely.

Installation is straightforward for anyone with basic mechanical skills and standard hand tools. The included stainless steel clamps make securing the hoses quick and reliable, reducing the risk of leaks and ensuring a tight seal. It is recommended to inspect the cooling system and replace any worn components during installation to maintain optimal performance.
