Kyosho Mini-Z AWD Alloy Rear Gear Box Cover by GPM MZA013A  [MZA013A]

Mini-Z AWD Alloy Rear Gear Box Cover

This alloy rear gear box cover is an aftermarket replacement part produced by GPM for Kyosho Mini-Z AWD models, sold as 1 pcs. It is an RC-scale accessory intended to replace the standard rear gearbox cover, using aluminum construction to provide a firmer mounting surface for the rear drivetrain while keeping weight low.

Compatibility is focused on Mini-Z AWD platforms including MR-03 AWD variants where the original cover is removable. Fitment uses the existing rear gearbox mounting points so no chassis modification is required beyond standard disassembly. The part is intended to accept the stock fasteners and mate with original drivetrain components.

Installation notes: remove the rear section cover using the original hardware, position the alloy cover over the gearbox housing, and secure with the original screws. Avoid overtightening to prevent thread damage and confirm pinion and spur gear mesh after reassembly. No additional tools or hardware are required beyond those normally used for Mini-Z maintenance.

Tuning role and maintenance: replacing the stock cover with an alloy unit can slightly stiffen the rear mounting area, which may affect drivetrain feel and consistency when tuning suspension or motor alignment. Regular inspection for wear and correct gear mesh is recommended; clean any debris and check screw torque after a few runs.
