This aluminum rear gear box cover is a bolt-on replacement for the original rear cover on Tamiya TA01, TA02 and DF01 chassis. It functions as a rigid top plate across the gearbox area, replacing the stock unit to deliver reduced flex where the gearbox meets the chassis.
Manufactured for the specified Tamiya platforms, the part arrives in red aluminium and secures using the OEM mounting points. Installation replaces the factory cover with the alloy piece while keeping screw positions and alignment; check gear mesh and ensure all screws are seated and torqued correctly after fitting.
From a tuning perspective the plate stiffens the rear mounting interface to keep gear alignment steadier when the car is under load, helping with repeatable gear-mesh and rear-end balance adjustments. Normal maintenance remains accessible through the same removal steps as the original cover.
