Construction & Design

The hoses are manufactured from premium-grade silicone reinforced with three layers of high-tensile fibers, providing exceptional resistance to heat, pressure, and environmental degradation. This multi-ply construction prevents swelling, cracking, and collapsing, common issues with stock rubber hoses. The silicone material also offers excellent flexibility, allowing the hoses to maintain their shape and integrity through engine vibrations and thermal expansion.

Each hose is precision-molded to match the exact contours and angles of the original equipment, ensuring a seamless fit without the need for modifications. The included stainless steel clamps are industrial-grade, embossed to prevent slippage and hose damage, and engineered to withstand corrosion for long-lasting secure connections.

Installation & Fitment

Installation is straightforward and designed to be a direct bolt-on replacement for the factory radiator hoses on the specified Jeep Grand Cherokee and Dodge Durango 5.7L Hemi models. No cutting, trimming, or additional modifications are necessary. The kit includes all necessary clamps for a secure and leak-free fit. It is important to note that this kit does not fit Dodge Durango 5.7L models equipped with an oil cooler from 2011 to 2021.

For best results, it is recommended to drain the coolant system before removal of the old hoses and to inspect all related cooling components during installation.
