What is the main advantage of using a Ford 8.8 axle with my Miata?

The Ford 8.8 axle housing is significantly stronger and more readily available than the stock Miata differential. This conversion allows your Miata to handle much higher horsepower and torque levels reliably.

Are there any special tools required for installing the bolt-on inner stubs?

While the bolt-on stubs simplify the process, proper installation of any axle conversion typically requires standard automotive tools. It's always recommended to consult the manufacturer's installation guide for specific tool requirements and procedures.

What else might I need to consider when installing this 8.8 axle conversion?

Beyond the axle shafts themselves, you'll likely need a compatible Ford 8.8 differential housing, mounting brackets to adapt it to the Miata chassis, and potentially driveshaft modifications. Ensure your transmission and clutch can handle the increased power.

About this part

Product Details

If you're looking to significantly upgrade the rear axle on your 1989-2005 Mazda Miata for more power, the Driveshaft Shop 8.8 Conversion Axle is a solid choice. This kit is designed to handle up to 550 horsepower, making it suitable for builds that go beyond stock power levels. It utilizes the robust Ford 8.8 inch differential housing, known for its strength and availability, and adapts it to your Miata's chassis.

This particular axle kit features 28-spline shafts, which are a good balance of strength and size for many performance applications. A key benefit of this setup is the inclusion of bolt-on inner stubs. This design simplifies installation compared to press-in stubs, allowing for a more straightforward swap. The shafts themselves are built to withstand the increased torque and stress that comes with a higher-horsepower Miata, ensuring reliability when you put the power down.

When undertaking a conversion like this, it's important to consider the entire drivetrain. This axle kit is a major component for handling increased power, but you'll also want to ensure your transmission, clutch, and differential are up to the task. The Driveshaft Shop is well-known for its driveline components, and this 8.8 conversion kit is a popular option for Miata owners looking to build a more powerful and durable rear end.
