​Reinforced Billet Differential Spacer Block for Mazda MX-5 Miata NA/NB

If you’re building your Mazda MX-5 Miata NA/NB for high performance, track use, or drifting, addressing weak points in the drivetrain is essential. One notorious failure point is the factory differential spacer, mounted between the differential and power plant frame (PPF). Made from brittle cast iron, the stock spacer struggles to handle the increased stress from hard driving, vibrations, and torque loads—especially in modified or high-horsepower builds.


Why Upgrade?

The stock spacer is prone to cracking, which can cause a differential that keeps loosening, moving, or making clunking noises. This can be both dangerous and annoying. In some cases, the spacer may even crack during removal, the PPF bolts can be completely seized into the spacer block due to corrosion. Our black anodized spacer eliminates this issue by preventing corrosion and ensuring smooth removal/installation. It's designed to be a direct replacement for the OEM spacer, but offers vastly superior strength and reliability, ensuring your drivetrain can handle whatever you throw at it.

Key Features:

  • Aerospace-Grade Material: Crafted from 7075-T6 aluminum, known for its incredible strength-to-weight ratio, ensuring durability without adding unnecessary weight.
  • Precision Engineering: Designed for a perfect fit with the differential location dowel bushes and PPF, eliminating any play between these components.
  • Premium Finish: Bead blasted and black anodized for corrosion resistance, combined with a sleek, durable appearance.
  • Professional Look: Topped with our epoxy gel logo for a professional, high-quality finish.

Built for Performance

Whether you’re chasing lap times on the track or perfecting your drift angles, this spacer is built to handle extreme conditions. Unlike the brittle cast iron OEM part, our billet aluminum spacer is designed to work under the stress of high-performance applications. It provides the strength and reliability your Miata needs to keep performing at its best, no matter how hard you push it.

Simply one of the ultimate upgrades needed for serious Miata enthusiasts who don't want trouble on track, but also for everyone looking to replace their broken spacer, and it's cheaper as the OEM version too!
