ARP Subaru EJ Series DOHC Custom Age Head Stud Kit
Whether you are doing a complete rebuild or standard maintenance, you need the right engine components to ensure your vehicle runs smoothly.
It is said that to be successful, you must identify a need and meet it. In the early 1970s, racing enthusiast Gary Holzapfel realized that many of his friends' broken engines were being caused by fastener failure. At the time, there were no commercially available 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 following years, the company grew from what was literally a backyard garage workshop 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 located 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). Please check whether the product can be installed on a Japanese vehicle (JDM) before ordering. (If you are unsure if a listed product is compatible with your vehicle, please feel free to contact us. Our support team will be happy to check for you.)
If you order without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if products are sorted by selecting the year, make, and model in the tabs on our top page, this does not necessarily mean they will fit Japanese model vehicles without modification.
All products have been translated into Japanese using translation software. There may be confusing expressions, so please contact us before ordering if you have any questions.
○Regarding Delivery
Shipping fees are paid at the time of checkout. Shipping cost estimates are calculated automatically when you enter your shipping address on the checkout page. For large items such as body parts, the automatically calculated shipping cost may occasionally differ significantly from 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 Japanese shipping, 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 confirm delivery times. Note that all products are transported by air; they are not shipped by sea.
○Regarding Japanese Vehicle Inspection (Shaken) Compatibility
All products handled by our company are designed and manufactured outside of Japan. Please note that they do not comply with the "Japanese Vehicle Inspection System," and we cannot provide documents such as strength calculation sheets for that purpose. 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 delivery damage to packaging boxes or products. Please understand that we will only provide returns, refunds, or replacement exchanges for items with delivery damage, defective products, or items different from those ordered, provided that you contact us within 7 days of receipt. Please note that for products sold through our company, all warranty-related support will be handled "exclusively through our company." We do not provide support through other companies or distributors located in Japan.
