Tamiya DT02/DT03/DT04 Hornet EVO Aluminum Gear Box Upgrade - JR-THNE06-BK by Jazrider  [JR-THNE06-BK]

Precision aluminum gearbox for Tamiya DT platforms

The JAZRIDER JR-THNE06-BK aluminum gear box is a purpose-built RC replacement housing engineered for direct fitment on Tamiya DT02, DT03, DT04 and Hornet EVO chassis. The single-piece black anodized body replaces the factory plastic case to provide a firmer mount and more consistent gear mesh under load.

Compatibility is restricted to the models listed above; retain the original bearings, spur and pinion gears from your existing assembly unless your build specifies replacements. The machined aluminum shell helps preserve alignment during heavy running and offers slightly improved heat dissipation compared with stock plastic, while adding a measurable change to chassis mass and balance.

Installation tips: move the internal components and fasteners into the new housing, confirm correct bearing seating and gear mesh as you assemble, and check clearance with the motor mount and suspension linkages before final torque. This item is a chassis-level hop-up rather than a full drivetrain kit.

Choose this JAZRIDER JR-THNE06-BK gear box to replace a worn plastic housing or to create a stiffer drivetrain mounting point for tuning on supported Tamiya DT platforms; always transfer parts carefully and verify gear alignment during fitment.
