ARP Acura B18A1/B1 Main Stud Kit
Whether it's a complete rebuild or standard maintenance, you need the right engine components to keep your vehicle running smoothly.
It is said that to be successful, you must identify a need and meet 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 commercial studs or bolts available to address this challenge. So, leveraging his years of experience manufacturing fasteners for a major aerospace subcontractor, Holzapfel founded ARP (Automotive Racing Products). Over the years that followed, the company grew from what was literally a backyard garage operation into a highly diversified manufacturer with seven operating entities in Southern California, totaling over 200,000 square feet. These include forging, heat treatment, machining, quality control finishing, and packaging/warehousing facilities in Santa Paula and Ventura, California.

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 will be no additional charges beyond the total amount you pay at checkout.
〇 Confirmation of Fitment
Our entire product database is based on North American specification vehicles (USDM), so please check whether the item can be installed on a Japanese specification vehicle (JDM) before placing your order. (If you are unsure whether the listed product fits your vehicle, please feel free to contact us. Our support team will investigate for you.)
If you place an order without confirming fitment, we cannot accept returns due to incompatibility.
Please note that even if items are sorted by selecting the year, manufacturer, and model in the tabs on our top page, it does not necessarily mean they will fit Japanese model vehicles without modification.
All product descriptions have been translated into Japanese using translation software. As there may be confusing expressions, please contact us if you have any questions before placing your order.
○ Regarding Shipping
Shipping costs are paid at the time of checkout. Shipping estimates 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 cost. In such cases, we will contact you individually via email.
All products are generally shipped internationally from our US warehouse. Unlike domestic shipping in Japan, international shipping takes about 7 to 14 days, so please allow yourself plenty of time when ordering. If you are in a hurry, please contact us in advance to check delivery times. Please note that all products are transported by air. They are not shipped by sea freight.
○ Regarding Compliance with Japanese Vehicle Inspection (Shaken)
All products we handle are basically designed and manufactured outside of Japan. Please note that they are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide documents such as strength calculation reports 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.
○ 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 box or the product. Please understand that we will only provide returns, refunds, or replacement products if you contact us within 7 days of receipt regarding products with shipping damage, defective products, or items that differ from your order. Please note that for products sold through us, all warranty-related support will be handled "exclusively through us." We do not provide support through other companies or distributors located in Japan.
