This differential spacer is a purpose-made RC accessory for controlling the spacing and alignment of gears on Mini-Z MR-015 cars that use the KZ-07/LB differential layout. It provides a discreet method to change clearance without modifying the diff case.
As a drop-in style part, the spacer is installed between differential components to alter axial play and mesh. It is suited to small setup changes aimed at improving drivetrain consistency, reducing play, and refining gear engagement at small scale.
To install: remove the differential, fit the spacer where your chassis specifies, then reassemble and verify smooth rotation and correct mesh before driving. Re-check for any binding and make fine adjustments to ensure uniform contact across the ring and pinion gears.
