ARP Mazda 2.5L (KL Series) V6 Head Stud Kit
Whether you are performing 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 noticed that many of his friends' broken engines were caused by fastener failure. At the time, there were no commercial studs or bolts available to address this challenge. So, utilizing his long-term experience manufacturing fasteners for a major aerospace subcontractor, 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 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
○ Regarding Import Consumption Tax
At Shaftoya 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.
○ Confirming Fitment
All product databases are primarily based on North American vehicles (USDM). Please confirm whether they can be installed on Japanese domestic vehicles (JDM) before placing your order. (If you are unsure if the listed product fits 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 fitment, we cannot accept returns due to incompatibility.
Please note that even if items are sorted by selecting the year, manufacturer, 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. 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 calculated automatically when you enter your delivery 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 check the delivery time. Furthermore, all products are transported by air. They are not shipped by sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compliance
Please be aware that all products we handle are basically designed and manufactured outside of Japan. They do not comply with "Japanese vehicle inspection 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 please install and use them at your own risk.
○ Regarding Warranty
Please check the contents immediately upon arrival. As all products are shipped internationally from outside Japan, the packaging box or the product itself may sustain shipping damage. Please understand that we will only handle returns, refunds, or replacements for products with shipping damage, defective products, or products different from what you ordered if you contact us within 7 days of receipt. Please note that for products sold through us, all warranty-related matters will be handled "exclusively through us." We do not provide support through other companies or distributors located within Japan.
