DSS 08-15 Subaru WRX 800HP Direct Fit Rear Axles RA8534X4-V2

These rear axles from Driveshaft Shop are built to handle up to 800 horsepower, using a proprietary spline design that offers a significant improvement over stock. They are a direct fit for the 2008 through 2015 Subaru WRX models, meaning installation is straightforward without the need for modifications. The axles are constructed with a strong, heat-treated alloy steel that’s been carefully selected for its durability under high stress.

The design incorporates larger, more robust components throughout, including the inner and outer CV joints, which are critical for transferring power smoothly and reliably, especially during hard acceleration or cornering. Driveshaft Shop has focused on strengthening the entire assembly, from the differential connection to the wheel hub, to ensure consistent performance and longevity even when pushing your WRX to its limits. This attention to detail means you can expect improved drivetrain reliability when you’re looking to increase your vehicle’s power output.

When upgrading your WRX's drivetrain for higher horsepower, these rear axles are a key component to consider. They are designed to work seamlessly with the factory differential and hubs, simplifying the installation process. If you're planning on significant power modifications, investing in a strong axle set like this is essential to prevent drivetrain failure and ensure your power is put to the ground effectively.
