Technical spacer for Mini-Z MR-015 diffs

This differential spacer is a compact tuning component for adjusting gear spacing and alignment on Mini-Z MR-015 cars that use the KZ-07/LB differential arrangement. It provides a measured way to alter clearance between differential elements without modifying the diff housing.

As a drop-in unit, the spacer is positioned between diff parts to change axial play and refine mesh. Use it for fine-tuning drivetrain behaviour, removing endplay, and achieving more consistent gear engagement during competitive running and track sessions.

Installation procedure: remove the differential assembly, insert the spacer at the specified location for your chassis, reassemble, then inspect gear mesh and rotation under hand. Verify there is no binding and that contact across the ring and pinion is even; iterate with small adjustments for optimal setup.

What diff arrangements does this target?

This spacer targets Mini-Z MR-015 assemblies using the KZ-07/LB layout. Confirm the internal layout of your diff before installing to ensure correct fit.

How should I verify correct mesh after fitting?

Check rotation by hand, listen for smooth engagement, and inspect contact pattern. Small shim increments are recommended to avoid over-tightening which can lead to friction and heat.
