HPS Silicone Radiator Hoses Kit

2007–2018 Jeep Wrangler JK 3.8L V6

Part #: 57-1220R-BLK

Overview

The HPS Silicone Radiator Hoses Kit is a premium upgrade designed specifically for the Jeep Wrangler JK equipped with the 3.8L V6 engine from 2007 through 2018. This kit replaces the original equipment manufacturer (OEM) radiator hoses with durable, high-performance silicone hoses that offer superior heat resistance and longevity. Ideal for Jeep enthusiasts looking to enhance their vehicle’s cooling system reliability, this kit helps prevent common issues such as coolant leaks and overheating caused by cracked or collapsed OEM hoses.

Whether you are restoring your Wrangler to factory condition or upgrading for enhanced durability, the HPS silicone hoses provide a perfect fit and reliable performance under demanding conditions. This kit is engineered to withstand the extreme temperatures found in the engine bay, ensuring consistent coolant flow and engine protection.

Key Features

Designed with both durability and performance in mind, the HPS Silicone Radiator Hoses Kit offers a range of benefits for Jeep Wrangler JK owners:

• Direct replacement or upgrade for OEM and aftermarket radiator hoses
• Constructed from premium grade, 3-ply reinforced silicone for high heat resistance
• Precisely molded bends and curves ensure perfect fitment without modifications
• Includes 100% stainless steel non-perforated embossed hose clamps that prevent hose damage during installation
• Engineered to prevent coolant leaks and overheating caused by damaged or collapsed hoses
• Race-proven design built for long-lasting durability under extreme temperature conditions
• Maximum operating temperature rating of 350°F (177°C)
• Silicone material offers improved resistance to cracking, swelling, and deterioration 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 high-quality, 3-ply reinforced silicone, a material known for its exceptional heat tolerance and flexibility. This construction allows the hoses to maintain structural integrity even under prolonged exposure to the intense heat generated by the engine and coolant system. The silicone’s resistance to cracking and collapsing significantly extends the service life compared to traditional rubber hoses.

Each hose is precision-engineered with the correct bends and curves to match the Jeep Wrangler JK’s radiator and engine layout, ensuring a seamless fit without the need for trimming or adjustments. The included stainless steel hose clamps are non-perforated and embossed, which prevents cutting into the silicone and provides a secure, leak-free seal.

Installation & Fitment

Installation of the HPS Silicone Radiator Hoses Kit is straightforward and designed to be a direct bolt-on replacement for the 2007–2018 Jeep Wrangler JK 3.8L V6 models. The hoses come pre-shaped to fit the factory routing, eliminating the need for modifications or custom fitting. The included stainless steel clamps simplify the installation process, providing a tight and reliable connection that resists loosening over time.

While installation can be completed by experienced DIYers, professional installation is recommended to ensure proper coolant system maintenance and leak-free operation. Regular inspection of coolant levels is advised when using silicone hoses due to their higher water vapor permeability compared to standard rubber hoses.
