Overview

The Mishimoto Silicone Radiator Hose Kit is a premium cooling system upgrade designed specifically for the 2004–2008 Dodge Ram 1500 equipped with the 5.7L HEMI engine.

Ideal for Dodge Ram owners looking to enhance reliability and prevent costly coolant system failures, these hoses provide peace of mind and improved longevity under demanding driving conditions.

Construction & Design

The Mishimoto radiator hoses are meticulously crafted using a multi-layer silicone construction that combines flexibility with rugged durability. The five-layer design incorporates premium silicone rubber reinforced with heat-resistant fibers, allowing the hoses to maintain their shape and integrity under extreme temperatures and pressure fluctuations. This advanced construction prevents common issues such as hose collapse, bulging, and premature deterioration that often affect OEM rubber hoses.

The hoses are precision-molded to match the exact contours and dimensions of the factory hoses, ensuring a seamless fit and reliable sealing. The bright red finish not only enhances engine bay aesthetics but also resists fading and discoloration over time.
