Perrin Performance Subaru WRX/STI Differential Lockdown Kit
Add drivetrain rigidity and precision to your Subaru's throttle input with the PERRIN Differential Lockdown Kit.
The PERRIN Differential Lockdown Kit consists of two aluminum plates and four urethane bushings, completely eliminating rear differential movement under all conditions. It covers and improves everything from performance street driving to track racing, drifting, and drag racing. Under such conditions, the OEM drivetrain (including the differential) twists and moves, creating a "mushy" or spongy feel during initial acceleration. The PERRIN Rear Differential Lockdown (DLS) locks the differential to zero out movement.

Before Ordering
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 Compatibility Confirmation
Our entire product database is based on North American vehicles (USDM), so please verify compatibility with Japanese vehicles (JDM) before ordering. (If you are unsure if the listed product is compatible with your vehicle, please feel free to contact us. Our support team will be happy to investigate 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, manufacturer, and vehicle model using 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 if you have any questions before placing an order.
○ Regarding Shipping
Shipping costs are paid at the time of checkout. Shipping estimates are calculated automatically once you enter your delivery address on the checkout page. For large items such as body parts, the actual shipping cost may occasionally differ significantly from the amount calculated automatically. In such cases, we will contact you individually via email.
In principle, all products are shipped internationally from our U.S. warehouse. Unlike domestic shipping in Japan, international shipping takes approximately 7 to 14 days, so please allow plenty of time for your order. If you are in a hurry, please contact us to confirm delivery dates in advance. All products are transported via air freight. They will not be shipped by sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
All products we handle are designed and manufactured outside of Japan. Please note that they are not compliant with the "Japanese Vehicle Inspection System (Shaken)," and we cannot provide documents such as strength calculation sheets for the Japanese inspection system. 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 inspect the contents immediately upon delivery. As all products are shipped internationally from outside Japan, there is a possibility of shipping damage to the packaging or the product. We will provide returns, refunds, or replacement exchanges only if you contact us within 7 days of receipt regarding damaged, defective, or incorrect items. 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.
