This alloy rear gear box cover is an aftermarket replacement for Kyosho Mini-Z AWD vehicles, supplied as 1 pcs. The aluminium construction offers a firmer mounting surface for the rear drivetrain while keeping added mass low.
Compatibility includes Mini-Z AWD platforms such as MR-03 AWD where the stock rear cover is removable. The cover mounts to the existing rear gearbox points so no permanent chassis changes are required. It is intended to work with original drivetrain components and the factory fasteners.
Fitting guidance: remove the existing rear cover using the original hardware, align the alloy cover over the gearbox housing, and fasten with the original screws. Avoid overtightening to prevent thread damage and check pinion to spur gear mesh after installation. No extra tools or hardware are normally needed beyond standard Mini-Z tools.
Use and maintenance: replacing the plastic cover with an alloy item can stiffen the rear mounting a little, which may alter drivetrain response during tuning. Inspect gear mesh regularly, remove debris, and verify screw torque after initial running sessions.
