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

Product information

Solve a common weak point in the Mazda MX-5 NA/NB drivetrain with our Reinforced Differential Spacer, perfect for high horsepower builds, track use, and drifting. The stock spacer, located between the differential and power plant frame (PPF), is made from brittle cast iron and often cracks under the stress of hard driving, vibrations, and torque loads—especially in modified vehicles.

Our spacer is crafted from aerospace-grade 7075-T6 aluminum, making it lightweight, incredibly strong, and built to handle extreme conditions. High precision fit to the differential location dowel bushes and PPF, ensuring zero play between these components.

Bead blasted and finished with a black anodized coating for corrosion resistance and topped with our epoxy gel logo, it combines durability with a premium look.

Whether you're attacking the track or sliding sideways on the drift course, this spacer provides the strength and reliability your MX-5 deserves. Don’t let a weak factory part hold you back—upgrade today!
