ARP Toyota 1.6L 4AGE 20V Head Stud Kit
Whether it's a complete rebuild or standard maintenance, you need the right engine components to keep your vehicle running smoothly.
They say that to be successful, you need to identify a need and meet it. In the early 1970s, racing enthusiast Gary Holzapfel noticed that many of his friends' blown 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 years of experience manufacturing fasteners for a major aerospace subcontractor, Mr. Holzapfel founded ARP (Automotive Racing Products). In the years that followed, the company grew from what was literally a backyard garage workshop into a highly diversified manufacturer with seven operations in Southern California, totaling over 200,000 square feet. These include forging, heat-treating, machining, quality control finishing, and packaging/warehousing facilities in Santa Paula and Ventura, California.
Before You Order
〇 Regarding 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Compatibility Check
Our entire product database is based on North American vehicles (USDM), so please verify compatibility with Japanese vehicles (JDM) before placing your order. (If you are unsure whether 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 place an order without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if items are sorted by selecting the year, manufacturer, and vehicle model using the tabs on our homepage, it does not necessarily guarantee that they will fit Japanese model vehicles 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, there may occasionally be a significant discrepancy between the automatically calculated shipping cost and the actual shipping cost. In such cases, we will contact you individually via email.
Basically, all products are 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 confirm the delivery date. Note that all products are transported by air freight. They are not shipped by sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compliance
Please note that all products we handle are designed and manufactured outside of Japan. They are not compliant with the "Japanese Vehicle Inspection System," and we are unable to provide strength inspection documents or similar paperwork for these regulations. 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 package immediately upon arrival. Since all products are shipped internationally from outside Japan, there may be shipping damage to the packing box or the product. Please understand that we will only provide returns, refunds, or replacement exchanges for items with shipping damage, defective products, or incorrect items if you contact us within 7 days of receipt. Furthermore, for products sold through us, all warranty-related support will be handled "exclusively through us." Please note that we do not handle support through other companies or distributors located in Japan.
