Tamiya DT02/DT03/DT04/Hornet EVO Aluminum Gear Box Cover - JR-THNE05-RD by Jazrider  [JR-THNE05-RD]

Aluminum gearbox lid for Tamiya DT platforms

This aluminum gear box cover is a direct-fit aftermarket component designed for RC-scale use on Tamiya DT02, DT03, DT04 and Hornet EVO chassis. It serves as a replacement or hop-up to protect the gearbox area, speed up maintenance access, and support light setup work without changing drivetrain geometry.

Fitment is straightforward: the part follows the outer mounting envelope for the listed Tamiya chassis and lines up with the common gearbox openings used on these models. Installers should check screw thread engagement and avoid forcing fasteners; use the original screw positions and recommended torque to prevent damaging plastic bosses.

Installation notes: remove the stock cover, inspect the gearbox seal and spur gear mesh, position the aluminum cover, and secure with the original screws. Because the cover is metal, take care not to over-torque near plastic mounting points and verify gear mesh after assembly. The aluminum design resists wear from repeated removal better than thin plastic covers.

Tuning role: this item is intended to aid durability and serviceability rather than alter suspension or drive behavior. Many hobbyists choose it for a stiffer cover that makes frequent access easier and for a cost-effective visual upgrade in red anodised finish.
