This aluminium spacer is an aftermarket motor locating part for Kyosho Mini-Z AWD and MR-03 AWD platforms. It sets the motor relative to the main gear so the pinion and spur mesh correctly, helping preserve drivetrain alignment when tuning or after maintenance.
Designed to support the gear combinations shown in the item listing, the spacer keeps motor pinion engagement stable. Supplied as a single pair, it is machined from aluminium alloy for rigidity and consistent refitting.
Installation tips: leave a little play in the mesh to prevent binding, re-check alignment after tightening the spacer, and use suitable thread locking if your setup sees vibration. This part is intended for 1:mini RC model use only.
