ARP BMW S65 4.0L V8 Head Stud Kit
Whether it is a complete rebuild or standard maintenance, proper engine components are essential for your vehicle to run smoothly.
It is said that to be successful, you must identify a need and fulfill it. In the early 1970s, racing enthusiast Gary Holzapfel noticed that many of his friends' blown engines were caused by fastener failure. At the time, there were no commercially available studs or bolts that could meet this challenge. So, leveraging his years of experience manufacturing fasteners for a major aerospace subcontractor, Mr. Holzapfel founded ARP (Automotive Racing Products). In the years that followed, the company grew from what was literally a backyard garage operation into a highly diversified manufacturer with seven entities in Southern California, totaling over 200,000 square feet. These include forging, heat treating, machining, quality control finishing, and packaging/warehousing facilities in Santa Paula and Ventura, California.
Before Ordering
〇 Regarding Import Consumption Tax
At Shaftoya Shopping Site, we cover the import consumption tax incurred at the time of import, so there will be no additional charges beyond the total amount paid at checkout.
〇Checking Compatibility
Our entire product database is based on North American vehicles (USDM), so please verify compatibility with Japanese specification vehicles (JDM) before placing your order. (If you are unsure whether the listed product is compatible with your vehicle, please feel free to contact us. Our support team will investigate for you.)
If you place an order without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if products 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 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.
〇 Regarding Shipping
Shipping costs are paid at the time of checkout. Shipping estimates are automatically calculated once 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.
Basically, all products are shipped internationally from our US warehouse. Unlike domestic shipping in Japan, international shipping takes about 7 to 14 days, so please allow plenty of time when ordering. If you are in a hurry, please contact us in advance to check the delivery time. Note that all products are transported by air. They are not shipped by sea freight.
〇 Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Please be aware that all products we handle are designed and manufactured outside of Japan. They are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide strength evaluation documents or similar paperwork for the Japanese inspection system. 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.
〇 Regarding Warranty
Please check 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 handle returns, refunds, or exchanges for shipping-damaged items, defective products, or incorrect items if notified within 7 days of receipt. Furthermore, for products sold through our company, warranty claims will be handled "exclusively through us." Please note that we do not facilitate correspondence through other companies or distributors located within Japan.
