The HPS black high-temperature 3-ply reinforced silicone radiator hose kit (Part Number: 57-1729-BLK) replaces the 1989–1994 Nissan Skyline GTR R32 RB26DETT twin-turbo stock OEM rubber upper and lower radiator coolant hoses (Part Numbers: 2150105U00, 2150372L00) using premium-grade, high-heat resistant materials that meet or exceed OE specifications (maximum temperature rating: 350°F). Compared to universal hoses from local auto parts stores, the HPS silicone radiator hose kit features the proper bends and curves for a perfect fit. The HPS silicone coolant hose kit includes 100% stainless steel non-perforated embossed hose clamps for easy installation without cutting the silicone hose. HPS silicone hoses prevent and resolve coolant leaks and engine overheating issues caused by cracked, damaged, or collapsed OEM rubber coolant hoses. With superior performance in extreme ambient and radiant temperature conditions, HPS silicone hoses can withstand the harsh high-temperature and high-pressure operating conditions of the engine, while maintaining peak efficiency during both daily driving and race competition. HPS silicone hose kits come with the HPS Performance Products limited lifetime warranty.
Before Ordering
〇 About Import Consumption Tax
At Shaftoya Shopping Site, we pay the import consumption tax incurred at the time of import on your behalf, so there will be no additional charges beyond the total amount paid at checkout.
〇 Confirmation of Fitment
All product databases are based on North American vehicles (USDM), so please confirm fitment for Japanese vehicles (JDM) before ordering. (If you are unsure if a listed product fits your vehicle, please feel free to contact us. Our support team will investigate for you.)
If an order is placed without confirming fitment, we cannot accept returns due to incompatibility.
Please note that even if items are sorted by selecting the year, manufacturer, and vehicle model using the tabs on our top page, this does not necessarily mean they will fit Japanese model vehicles 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 Delivery
Shipping costs are paid at the time of checkout. Shipping estimates are calculated automatically once you enter your shipping address on the checkout page. For large items such as body parts, the actual shipping cost may occasionally differ significantly from the amount calculated automatically. In such cases, we will contact you individually via email.
Basically, all products are shipped internationally from our U.S. warehouse. Unlike domestic delivery within Japan, international delivery takes about 7 to 14 days, so please order with time to spare. If you are in a hurry, please contact us in advance to check the delivery time. Please note that all products are transported by air; they are never shipped by sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
The products we handle are basically all designed and manufactured outside of Japan. Please be aware that they are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide strength evaluation documents or similar paperwork for these requirements. Therefore, all parts are sold for the purpose of "use on circuits, private property, 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, packaging boxes and products may sustain shipping damage. We only provide returns, refunds, or replacement items if notified within 7 days of receipt for products with shipping damage, defective items, or items different from what was ordered. Please understand that for products sold through us, we will handle warranty-related matters "exclusively through us." We do not provide support through other companies or distributors located within Japan.
