Kyosho Mini-Z AWD Aluminium Motor Spacer and Gear Options MZA018/A3 by GPM  [MZA018/A3]

Upgrade spacer for Mini-Z AWD drivetrains

This aluminium motor spacer and matched gear set is supplied as 1 pr and intended for Kyosho Mini-Z AWD cars. It positions the motor so the pinion aligns with the main spur on MR-03 AWD platforms, helping to stabilise mesh and reduce uneven wear.

The assembly pairs an aluminium spacer with three motor gear options and the corresponding main gear pairings listed in the product title, enabling straightforward pinion swaps to change gearing without modifying the gearbox housing. The aluminium spacer maintains axial alignment better than many plastic mounts under repeated loading.

Fitment advice: remove the standard motor mount parts, fit the spacer between motor and chassis to obtain correct pinion engagement, then install the selected motor gear ensuring a clean mesh with the chosen main gear. After assembly check backlash and free spin, apply threadlocker where appropriate and avoid forcing gear engagement to prevent early wear.

Tuning guidance: swapping pinion and spur combinations tunes acceleration versus top speed on small circuits, while the spacer keeps mesh consistent across setup changes. This is a component for RC Mini-Z AWD competition and practice cars and is not intended for full-scale vehicles.
