The Tamiya 49203 Rear Gear Case Reinforcement Kit is made to reinforce the rear section of the TA04 chassis, adding rigidity to the gearbox area. The added support helps keep gears and bearings aligned during heavy use.
Reducing gearbox flex gives more predictable throttle response and steadier handling, especially when pushing the car hard. The Tamiya 49203 lowers the risk of sudden drivetrain failures by stabilising the rear internals.
Fitting the Tamiya 49203 is generally quick for anyone who has worked on a TA04 before. Follow standard torque settings, check gear mesh after assembly, and use common hand tools to complete the job.
