• Significantly reduces the risk of hose failure under extreme operating conditions
• Compatible with daily driving and high-performance applications

Construction & Design

The hoses are crafted from reinforced silicone, a material known for its exceptional heat resistance and durability compared to standard rubber hoses. This silicone compound is engineered to endure temperatures up to 350°F, making it ideal for the demanding thermal environment of the 5.7L Hemi engine. The hoses feature precise bends and contours that replicate the original equipment manufacturer’s design, ensuring a seamless fit without the need for modifications.

Each hose is paired with stainless steel non-perforated embossed clamps that provide a secure seal without cutting into the silicone, preserving hose integrity and extending service life. This combination of materials and design results in a robust cooling system upgrade that resists cracking, swelling, and premature failure common in OEM rubber hoses.

Installation & Fitment

The HPS Silicone Radiator Hoses Kit is a direct replacement for the factory upper and lower radiator hoses on the specified Chrysler and Dodge 5.7L Hemi models. Installation is straightforward and requires no special tools or modifications. The included stainless steel clamps simplify the process, ensuring a tight, leak-free connection. Regular inspection of coolant levels is recommended when using silicone hoses, as silicone has a higher water permeation rate compared to standard EPDM rubber hoses.

What's Included

• Upper radiator hose (reinforced silicone)
• Lower radiator hose (reinforced silicone)
• Set of stainless steel non-perforated embossed hose clamps
• Installation instructions
