ARP 87-92 Supra MK3 Undercut Head Stud Kit
Whether you are performing a complete rebuild or standard maintenance, you need the right engine components to keep your vehicle running smoothly.
It is said that to be successful, you must identify a need and fulfill 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 commercial studs or bolts available to meet this challenge. So, drawing on his years of experience manufacturing fasteners for a major aerospace subcontractor, Holzapfel founded ARP (Automotive Racing Products). Over the ensuing 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 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 on your behalf, so there will be no additional charges beyond the total amount paid at checkout.
〇Confirming Fitment
Our entire product database is based on North American vehicles (USDM). Please confirm the compatibility with Japanese vehicles (JDM) before ordering. (If you are unsure whether the listed product fits your vehicle, please feel free to contact us. Our support team will investigate for you.)
If you order without confirming fitment, we cannot accept returns due to incompatibility.
Please note that even if items are sorted by selecting the year, manufacturer, and model on our top page tabs, it does not necessarily mean 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 Delivery
Shipping costs are paid at the time of payment. 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 occasionally differ significantly from the automated calculation. 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 enough time when ordering. 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 designed and manufactured outside of Japan. Please understand that they are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide strength calculation documents or similar paperwork for the Japanese inspection system. 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 inspect the contents immediately upon arrival. As all products are shipped internationally from outside Japan, there is a possibility of shipping damage to the packing boxes or products. 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 our company, all warranty-related support will be handled "exclusively through us." Please note that we do not handle support through other companies or distributors located within Japan.
