This aluminium gear box cover is an aftermarket replacement panel intended for the gearcases used on Tamiya DT02, DT03, DT04 and Hornet EVO chassis. It offers a durable substitute to the original plastic cover, improving the mounting surface and tidying the gearbox area on touring models.
Installation follows the original panel's mounting pattern: remove the plastic cover, align the aluminium part with the existing bosses, and fasten with the model's screws. Check gear mesh and shaft alignment after fitting to ensure smooth operation. The cover is supplied in a black finish and is designed for the standard gearbox configuration of the listed Tamiya models.
Used in tune-ups where rigidity and repeatability are required, the panel is useful when swapping spurs, fitting upgraded bearings, or carrying out maintenance that benefits from a more stable panel than molded plastic. This is a body/structural accessory and does not include drivetrain or electronic parts.
