The Speed Tek 10-inch quick-change skid plate is a protective plate for differentials made from 350MPa high-strength steel. Because quick-change differentials feature larger gears and components to increase the strength of the differential unit itself, road clearance can become an issue depending on the mounting position. Among these areas, the most vulnerable part is the lower rear section of the differential, and installing this skid plate can protect the differential from impact with the road surface.
It is an essential item, particularly for protecting the differential housing from impacts when running off-track or over rumble strips.
What is 350MPa?
350MPa is a value indicating the yield strength of the material, meaning it is resistant to deformation and can maintain its original shape even when a force of 350 megapascals (= approximately 35kgf/mm²) is applied.
Steel that is resistant to bending and highly durable against impact

Before ordering
〇Regarding import consumption tax
At the Shaft-Ya 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
Since all product databases are based on North American vehicles (USDM), please confirm whether or not they can be installed on Japanese vehicles (JDM) before placing your order. (If you are unsure if a listed product is compatible with your vehicle, please feel free to contact us. Our support team will be happy to look into it for you.)
If you place an order without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if products are sorted by selecting the year, manufacturer, and vehicle model in the tabs on our homepage, 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 shipping
Shipping costs are paid at the time of payment. Shipping estimates are automatically calculated on the checkout page once you enter your shipping address. For large items such as body parts, there are rare cases where the automatically calculated shipping cost differs significantly from the actual cost. In such cases, we will contact you individually via email.
All products are generally shipped internationally from our U.S. warehouse. Unlike domestic shipping within Japan, international shipping takes approximately 7 to 14 days, so please allow 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; they are not shipped by sea.
○Regarding compliance with Japanese vehicle inspections (Shaken)
All products we handle are basically designed and manufactured outside of Japan. Please note that they are not compliant with the "Japanese vehicle inspection system," and we are unable to provide strength calculation documents for that purpose. 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 warranties
Please check the contents immediately upon arrival. Since all products are shipped internationally from outside Japan, there may be shipping damage to the packaging or the product itself. Please understand that we will only provide returns, refunds, or replacement products if you contact us within 7 days of receipt regarding items with shipping damage, defective products, or incorrect items. Furthermore, for products sold through us, warranty-related support will be provided "exclusively through us." Please note that we do not handle support through other companies or distributors located within Japan.
