ARP 94+ Mitsubishi 4G63 M11 Custom Age 625+ Head Stud Kit
Whether you're performing a complete rebuild or just standard maintenance, having the right engine components is essential for your vehicle to run smoothly.
They say 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 caused by fastener failure. At the time, there were no off-the-shelf studs or bolts that could handle this challenge. So, utilizing his years of 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 operation 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 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 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 confirm whether the product can be installed on a Japanese domestic vehicle (JDM) before ordering. (If you are unsure whether a listed product is compatible with your vehicle, please feel free to contact us. Our support team will 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 on our homepage tabs, it does not necessarily mean they will fit Japanese market 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 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.
All products are generally 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 to check delivery times in advance. Note that all products are transported by air; they are not shipped by sea.
○ Regarding Japanese Road Legal Compliance (Shaken)
Our products are basically all designed and manufactured outside of Japan. Please understand that they are not compliant with "Japanese Road Legal Standards (Shaken)," and we cannot provide strength calculation reports or similar documentation for Japanese road legal purposes. Therefore, all parts are sold for use on "circuits, private land, or off-road," and installation and use are at your own risk.
○ Regarding Warranty
Please check the contents of your package immediately upon arrival. As all products are shipped internationally from outside Japan, there may be shipping damage to the packaging or the product. We will only handle returns, refunds, or replacements for damaged items, defective products, or items different from what was ordered if contacted within 7 days of receipt. Please note that for products sold through us, warranty support will be handled "exclusively through us." We do not provide support through other companies or distributors located within Japan.
