ARP Nissan SR20DET Head Stud Kit
Whether it's a complete rebuild or standard maintenance, having the right engine components is essential for your vehicle to run smoothly.
It is said that to be successful, you must identify a need and fulfill it. In the early 1970s, racing enthusiast Gary Holzapfel realized 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 handle this challenge. So, leveraging his long experience manufacturing fasteners for a major aerospace subcontractor, Holzapfel founded ARP (Automotive Racing Products). In the years since, the company has grown from what was literally a backyard garage workshop into a highly diversified manufacturer with seven facilities 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 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 Fitment
All of our product databases are based on North American vehicles (USDM), so please verify compatibility with Japanese 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 look into it for you.)
If you 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 model in the tabs on our top page, it does not necessarily mean they will fit Japanese models without modification.
All product descriptions 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 costs are paid at the time of payment. Shipping estimates are calculated automatically once 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.
Basically, all products are shipped internationally from our U.S. warehouse. Unlike domestic shipping in 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 items are transported by air; they are not shipped via sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Please be aware that all products we handle are designed and manufactured outside of Japan. They are not compliant with "Japanese Vehicle Inspection (Shaken) standards," and we cannot provide strength calculation documents or similar paperwork for these standards. 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 inspect the contents immediately upon delivery. As all products are shipped internationally from outside Japan, packaging boxes or the products themselves may sustain shipping damage. Please understand that we will only provide returns, refunds, or replacement exchanges for items with shipping damage, defective products, or incorrect items if notified within 7 days of receipt. Please also note that for products sold through our company, all warranty-related support will be handled "exclusively through us." We do not provide support through other companies or distributors located within Japan.
