HPS Silicone Radiator Hoses Kit

2002–2010 Dodge Ram 5.9L Diesel & 6.7L Diesel

Part #: 57-1322-BLK

Overview

The HPS Silicone Radiator Hoses Kit is a premium cooling system upgrade designed specifically for Dodge Ram trucks equipped with 5.9L and 6.7L diesel engines from 2002 to 2010. This kit replaces the factory lower and upper radiator hoses with durable, high-quality silicone hoses engineered to withstand extreme temperatures and harsh under-hood conditions. Ideal for owners seeking a reliable OEM replacement or a performance upgrade, these hoses help prevent coolant leaks and overheating issues caused by cracked or collapsed original hoses.

Whether you are maintaining a daily driver or enhancing a diesel truck for heavy-duty use, this kit delivers long-lasting durability and a precise fitment that ensures hassle-free installation and dependable operation.

Key Features

Designed with both durability and performance in mind, the HPS Silicone Radiator Hoses Kit offers the following key benefits:

• Premium-grade, high-heat resistant 3-ply reinforced silicone construction
• Engineered with correct bends and curves for perfect OEM fitment
• Includes 100% stainless steel non-perforated embossed hose clamps that prevent hose damage during installation
• Prevents coolant leaks and overheating caused by damaged or collapsed OEM hoses
• Race-proven design built to withstand prolonged exposure to under-hood heat and coolant temperatures
• Maximum operating temperature rating of 350°F (177°C)
• Significantly lower risk of hose failure compared to standard rubber hoses
• Recommended regular coolant level checks due to higher water permeation rate compared to EPDM rubber hoses

Construction & Design

The hoses in this kit are crafted from premium silicone material reinforced with a 3-ply fabric layer to provide exceptional strength and flexibility. This construction allows the hoses to resist cracking, collapsing, and deformation under high heat and pressure conditions commonly found in diesel engine cooling systems. The silicone material also offers superior resistance to oil, chemicals, and environmental contaminants compared to traditional rubber hoses.

Each hose is precisely molded with factory-correct bends and curves to ensure a seamless fit without the need for modifications. The included stainless steel clamps are embossed and non-perforated, which prevents cutting or damaging the silicone during installation, ensuring a secure and leak-free connection.

Installation & Fitment

The HPS Silicone Radiator Hoses Kit is designed for direct bolt-on installation on 2002 through 2010 Dodge Ram trucks equipped with 5.9L and 6.7L diesel engines. No cutting or trimming is required, making the upgrade straightforward for both professional mechanics and experienced DIY enthusiasts. The kit replaces the OEM lower and upper radiator hoses, addressing common failure points to restore reliable coolant flow and prevent overheating.

For optimal performance and longevity, it is recommended to regularly check coolant levels when using silicone hoses, as their water permeation rate is higher than standard EPDM rubber hoses.

What's Included

• High-heat resistant 3-ply reinforced silicone lower radiator hose
• High-heat resistant 3-ply reinforced silicone upper radiator hose
• 100% stainless steel non-perforated embossed hose clamps for secure installation
