The JAZRIDER JR-THNE06-BK aluminum gear box is an RC-scale replacement housing designed for direct fitment on Tamiya DT02, DT03, DT04 and Hornet EVO platforms. The single-piece black anodized casing is intended to replace the factory plastic unit where increased rigidity and more consistent gear mesh are required.
Compatibility is limited to the models specified; transfer bearings, spur and pinion gears from the original assembly unless replacements are part of your build plan. The machined aluminum body helps maintain alignment under load and can assist with heat transfer compared with plastic, while adding modest weight that will affect chassis balance.
Installation notes: move the original internals and fasteners into the new housing, check bearing seating and gear mesh during assembly, and confirm clearance with the motor mount and suspension linkages before final tightening. The item is supplied as a chassis-level hop-up rather than a complete drivetrain package.
Opt for the JAZRIDER JR-THNE06-BK when replacing worn plastic housings or when you need a firmer drivetrain mounting point for tuning on supported Tamiya DT platforms; ensure proper parts transfer and gear alignment during installation.
