ARP Toyota Supra B58B30 12pt Head Stud Kit
Whether performing a complete rebuild or standard maintenance, you need the right engine components to ensure your vehicle runs smoothly.
It is said that to succeed, you must identify a need and fulfill it. In the early 1970s, racing enthusiast Gary Holzapfel noticed that many of his friends' broken engines were caused by fastener failure. At the time, there were no commercially available studs or bolts that could meet this challenge. So, drawing on his years of experience manufacturing fasteners for a major aerospace industry subcontractor, 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 About Import Consumption Tax
At Shafutoya 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Confirmation of Compatibility
All product databases are based on North American vehicles (USDM). Please confirm whether the product can be installed on a Japanese domestic vehicle (JDM) before placing your order. (If you are unsure if a 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 items are sorted by selecting the year, manufacturer, and vehicle model on the tabs on our top page, it 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.
○ About Delivery
Shipping costs are paid at the time of checkout. Shipping quotes are calculated automatically 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.
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 confirm the delivery date. Please note that all products are transported by air; they are never shipped by sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
All products we handle are 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 for the Japanese vehicle inspection system. 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 check the contents immediately upon receipt of your product. As all products are shipped internationally from outside Japan, there may be shipping damage to the packing box or the product itself. Please understand that for products with shipping damage, defective products, or products different from what was ordered, we will only handle returns, refunds, or exchanges if contacted within 7 days of receipt. Additionally, for products sold through us, warranty support will be handled "exclusively through us." Please note that we do not coordinate with other companies or agencies located in Japan.
