This aluminum gear box cover from JAZRIDER is a direct-fit aftermarket component designed for RC-scale use on Tamiya DT02, DT03, DT04 and Hornet EVO chassis. It is intended as a replacement or hop-up to protect the gearbox area, aid in routine maintenance, and support modest tuning and setup changes without altering drivetrain geometry.
Compatibility and fitment are straightforward: the part matches the outer mounting envelope for the listed Tamiya chassis and aligns with standard gearbox openings used on those models. Installers should verify screw thread engagement and avoid forcing fasteners; use the factory screw locations and torque to prevent thread damage.
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 around plastic bosses and confirm gear mesh after final assembly. The cover can simplify repeated access during maintenance since aluminum resists wear from repeated removal compared with thin plastic covers.
Tuning role: this part serves as an accessory to support chassis durability and maintenance workflows rather than changing suspension or drive characteristics. Hobbyists use it when they prefer a more rigid cover for frequent servicing or as a cost-effective visual upgrade in red anodised finish.
