Stiffen the gearbox area for improved handling

This JR-THNE05-GU aluminum gear box cover is an aftermarket RC-scale plate engineered to fit Tamiya DT02, DT03, DT04 and Hornet EVO chassis names in the product title. The gun metal finish provides a direct-fit external shell that mounts to existing gearbox screw points on the listed Tamiya platforms.

As a tuning component, the aluminum plate raises local chassis stiffness around the gearbox, offering more consistent behavior under aggressive driving and reducing flex-related drivetrain variance. It provides a tougher surface than many stock plastic covers while preserving access to internal gears for servicing.

Fitment is generally straightforward: remove the stock cover, confirm gear mesh, position the JR-THNE05-GU and secure with the original fasteners. Recheck spur and pinion clearance and ensure free rotation after installation to avoid drivetrain binding.

Compatibility

  • Tamiya DT02
  • Tamiya DT03
  • Tamiya DT04
  • Tamiya Hornet EVO

Will this cover affect handling or chassis balance?

Adding a metal cover increases stiffness and a small amount of weight at the gearbox, which can improve consistency under load; the effect on handling is subtle but beneficial for aggressive driving and precise setups.

Should I expect weight penalties when upgrading?

There is a minor weight increase compared with plastic covers; consider the tradeoff between added durability and the small mass change when tuning for peak performance.

Is this suitable for competitive tuning builds?

Yes. For setups where gearbox stiffness and repeatability matter, the aluminum cover is a common upgrade to reduce flex and improve drivetrain consistency during tuning.
