ARP Honda H23A Head Stud Kit
Whether performing a complete rebuild or standard maintenance, you need the right engine components for your vehicle to run 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 off-the-shelf studs or bolts that could address this challenge. So, utilizing his years of experience manufacturing fasteners for a major aerospace subcontractor, Holzapfel founded ARP (Automotive Racing Products). Over the subsequent years, 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 treatment, machining, quality control finishing, and packaging/warehousing facilities in Santa Paula and Ventura, California.

Before You Order
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 Confirming Fitment
As all of our product databases are based on North American vehicles (USDM), please confirm the compatibility with Japanese vehicles (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 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 on our top page, it does not necessarily guarantee fitment on 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. Shipping estimates are automatically calculated when 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 automatic calculation. In such cases, we will contact you individually via email.
In principle, all products are shipped internationally from our US warehouse. Unlike domestic shipping within Japan, international shipping takes about 7 to 14 days, so please allow plenty of time for your order. If you are in a hurry, please contact us in advance to confirm delivery times. Note that all products are transported by air; they are not shipped by sea.
○ Regarding Compliance with Japanese Vehicle Inspection (Shaken)
Essentially, all products we handle are designed and manufactured outside of Japan. Please understand 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 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 delivery. As all products are shipped internationally from outside Japan, there may be delivery damage to packing boxes or the products themselves. Please understand that we will only handle returns, refunds, or replacement exchanges if you contact us within 7 days of receipt regarding products with delivery damage, defects, or items that differ from your order. Furthermore, for products sold through us, warranty-related support will be handled "only through our company." Please note that we do not handle coordination through other companies or agencies located within Japan.
