This aluminium gear box cover is offered as an aftermarket, direct-fit option for Tamiya DT02, DT03, DT04 and Hornet EVO chassis. It is designed to protect the gearbox region, make maintenance faster, and assist with modest setup changes without affecting basic drivetrain geometry.
Fitment notes: the part follows the external mounting outline for the listed Tamiya chassis and matches the usual gearbox openings used by those kits. Installers should verify screw alignment and thread engagement, and avoid forcing hardware; use the stock screw points and reasonable torque to avoid damaging plastic mounting posts.
How to install: remove the stock cover, check the gearbox seal and spur/pinion mesh, place the aluminium cover, and secure with the original screws. Because the cover is metal, take care not to over-torque around plastic bosses and recheck gear mesh after final assembly. The aluminium option simplifies repeated access during servicing since it resists wear from removal better than thin plastic.
Tuning perspective: the cover is intended to help with durability and service workflows rather than change suspension or drivetrain dynamics. Many RC enthusiasts select the red anodised finish as both a functional and visual upgrade when regular service access is needed.
