HPS high-temperature 3-ply reinforced silicone coolant hose kits are designed to replace stock OEM rubber upper and lower radiators, upper bypass hoses, and coolant expansion tank hoses, which can eventually weaken over time and lead to premature failure. Featuring premium-quality silicone and a racing-inspired design, this silicone hose kit can withstand the engine's harsh high-temperature and high-pressure operating conditions while maintaining peak efficiency during competition or daily driving. This silicone radiator hose kit includes a 5-way aluminum joiner to connect the branches of the lower radiator hose. The aluminum joiner is significantly stronger than the stock plastic part, reducing the potential for cooling system failure. HPS silicone hose kits have the correct bends and sizes for a perfect fit and replacement for OEM rubber coolant hoses. Compared to universal hoses available at local auto parts stores, HPS silicone hose kits are much easier to handle. Maximum temperature rating: 350 degrees Fahrenheit. Includes 100% stainless steel clamps for easy installation.
Before Ordering
〇Regarding Import Consumption Tax
At the Shaftoya shopping site, we pay the import consumption tax incurred at the time of import on your behalf, so there are no additional charges beyond the total amount paid at checkout.
〇Compatibility Confirmation
Our entire product database is based on North American vehicles (USDM). Please confirm compatibility with Japanese vehicles (JDM) before placing your order. (If you are unsure whether a listed product is compatible with your vehicle, please feel free to contact us. Our support team will investigate for you.)
If you order without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if items are sorted by selecting the year, manufacturer, and vehicle model in the tabs on our homepage, it does not necessarily guarantee that they will fit Japanese models without modification.
All products have been translated into Japanese using translation software. As there may be confusing expressions, please contact us before ordering if you have any questions.
○Regarding Shipping
Shipping costs are paid at the time of payment. Estimates for shipping costs are automatically calculated when you enter your shipping address on the checkout page. For large items such as body parts, there may occasionally be a significant discrepancy between the automatically calculated shipping cost and the actual shipping cost. In such cases, we will contact you individually via email.
All products are generally shipped internationally from our warehouse in the United States. Unlike domestic shipping in Japan, international shipping takes 7 to 14 days, so please allow yourself enough time when ordering. If you are in a hurry, please contact us in advance to confirm the delivery date. Note that all products are transported by air freight. They are not shipped by sea freight.
○Regarding Japanese Vehicle Inspection (Shaken) Compatibility
The products we handle are basically all designed and manufactured outside of Japan. Please note that they are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide strength calculation documents or similar paperwork for this purpose. Therefore, all parts are sold for the purpose of "use on circuits, private land, or off-road," and installation and use are at your own risk.
○Regarding Warranty
Please inspect the contents immediately upon arrival. Since all products are shipped internationally from outside Japan, there may be shipping damage to the packaging or the product itself. Please understand that we will only provide returns, refunds, or replacements for damaged, defective, or incorrect items if you contact us within 7 days of receipt. Furthermore, for products sold through our company, warranty-related support will be handled "exclusively through us." Please note that we do not provide support through other companies or distributors located in Japan.
