This JR-THNE05-GU aluminium gear box cover is an aftermarket, scale replacement intended for the Tamiya DT02, DT03, DT04 and Hornet EVO chassis referenced in the title. The gun metal plate is made to locate on the original gearbox mounting points and use the existing screw holes on those Tamiya platforms.
The aluminium cover provides a stronger mounting surface than many stock plastic covers, helping the chassis resist deformation and offering improved protection against abrasion. It is designed to retain access to gearbox internals so service and adjustments remain possible.
Installation follows standard procedures: remove the factory cover, inspect gear mesh and seals, position the JR-THNE05-GU and secure with the original fasteners. Once fitted, rotate the drivetrain by hand to confirm there is no binding or misalignment.
