The JR-THNE06-LB aluminum gear box is a machined aftermarket replacement for Tamiya DT02, DT03, DT04 and Hornet EVO chassis. Finished in blue anodize, it replaces the factory plastic housing to offer a stiffer mounting surface for spur and pinion gears and to better withstand higher-load tuning setups.
Fitment: built as a direct-fit option for the listed Tamiya models, the housing maintains original mounting and bearing locations so pulley, spur gear and motor alignment are preserved. Inspect gears and bearings when servicing and confirm bearing seating before final assembly. Use thread-lock where metal fasteners share threads, applying as required.
Benefits: installing an aluminum gearbox reduces flex in the spur area, improving mesh stability under increased torque and helping with heat dispersion versus plastic housings during prolonged use.
A suitable aftermarket upgrade for hobbyists seeking a stronger, direct-fit gearbox to enhance drivetrain stiffness and gear reliability on Tamiya DT-series vehicles.
