Mini-Z AWD Rear Gearbox Cover Aluminum Upgrade MZA013A by GPM  [MZA013A]

Rear gearbox alloy cover for Mini-Z AWD

This alloy rear gear box cover is an aftermarket replacement made for Kyosho Mini-Z AWD cars and is sold as 1 pcs. The aluminum construction gives a firmer mounting surface for the rear drivetrain while retaining a low mass to limit added inertia.

Compatibility targets Mini-Z AWD platforms, including MR-03 AWD variants that have a removable rear cover. The part uses the stock rear gearbox mounting points so no chassis cutting or special modification is required. It mates with the original drivetrain components and accepts the factory fasteners.

Installation notes: remove the standard rear cover with the original hardware, place the alloy cover onto the gearbox housing, and refit using the original screws. Take care not to overtighten screws to protect threads and verify pinion to spur gear mesh after reassembly. No extra hardware or special tools are normally required beyond routine Mini-Z maintenance tools.

Tuning and upkeep: swapping the plastic cover for an alloy unit can stiffen the rear mounting area slightly, which may change drivetrain feel during suspension or motor alignment tweaks. Inspect gear mesh routinely, clear debris, and recheck screw torque after the first few runs.
