This alloy rear gear box lower tray is an aftermarket replacement produced by GPM for Kyosho Mini-Z AWD applications and marked as the economy version. It is supplied as a 1 pcs set and includes the required screws for mounting. The part is an RC-scale accessory intended to replace the stock lower tray on compatible Mini-Z AWD layouts.
Functionally the tray provides a rigid mounting base for the rear gearbox section on MR-03 AWD style chassis, helping maintain alignment of the spur and pinion gear train when compared to some softer plastic lower trays. As an economy alloy option it focuses on basic mechanical improvement rather than high-end surface finishing.
Installation notes: remove the rear gearbox assembly per your chassis manual, fit the alloy lower tray in place of the original lower cover, and secure with the supplied screws using an appropriate hex driver. Take care to avoid over-tightening fasteners and to check gear mesh and bearing seating after installation. The part is useful for routine maintenance, replacement of damaged plastic parts, or modest tuning changes where increased rigidity is desired.
