This differential spacer is an RC-scale accessory intended to control gear spacing and alignment on Mini-Z MR-015 setups that use the KZ-07/LB differential arrangement. It provides a minimal-impact method to alter clearance between differential components without changing the original diff case.
Designed as a drop-in item, the spacer sits between diff elements to adjust axial play and improve mesh. Fit it when you need small refinements to drivetrain feel, to tighten gear contact, or to eliminate play that affects throttle control at miniature scale.
Fitment is simple: take out the differential assembly, insert the spacer according to your chassis layout, reassemble and check gear mesh and free rotation before driving. After installation, inspect for binding and make any minor tweaks needed to preserve even contact across the ring and pinion.
