ARP Honda D16A / D16Z M10 Head Stud Kit
Whether it's a complete rebuild or standard maintenance, you need the right engine components for your vehicle to run smoothly.
They say 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 that time, there were no off-the-shelf studs or bolts that could address 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 since, the company has grown from what was literally a backyard garage operation into a highly diversified manufacturer with seven entities in Southern California totaling more than 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 Shaft-ya Shopping Site, we pay the import consumption tax incurred upon import on your behalf, so there will be no additional charges beyond the total amount paid at checkout.
〇Verification of Fitment
Since our entire product database is based on North American vehicles (USDM), please confirm whether parts can be installed on Japanese domestic vehicles (JDM) before placing your order. (If you are unsure if a listed product fits your vehicle, please feel free to contact us. Our support team will be happy to check for you.)
If you place an order without confirming fitment, 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 mean they will fit 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 checkout. Shipping estimates are calculated automatically when you enter your shipping address on the checkout page. For large items such as body parts, the actual shipping cost may significantly differ from the automatically calculated amount in rare cases. In such instances, we will contact you individually via email.
All products are generally shipped internationally from our US warehouse. Unlike domestic shipping within Japan, international shipping takes about 7 to 14 days, so please order with plenty of time. 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 not shipped by sea.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
All products we handle are fundamentally designed and manufactured outside of Japan. Please note that they are not compliant with "Japanese vehicle inspection standards," and we cannot provide documents such as strength calculation sheets 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 of your order as soon as it arrives. As all products are shipped internationally from outside Japan, there may be shipping damage to the packing boxes or the products themselves. Please understand that we will only provide returns, refunds, or replacements for products with shipping damage, defective items, or items different from what was ordered if you contact us within 7 days of receipt. Please note that for products sold through us, we will handle all warranty-related matters "exclusively through us." We do not handle support through other companies or distributors located within Japan.
