Keep your TB-04 drivetrain true with the 51547

The Tamiya 51547 - RC TB-04 One-Way/Gear Differential Unit Ring Gear Set (40T) is a practical service part for TB-04 chassis owners who want reliable gear engagement. The kit includes the one-way mechanism plus the 40 tooth ring to restore consistent torque flow under load.

Driving benefits to expect

Fitting the 51547 reduces play in the drivetrain and delivers a steadier rear response when exiting corners, which can help drivers stay predictable through a range of turn types. The 40T ring is specified for routine durability during normal use.

Service and fitment guidance

Replacing the ring gear is a standard maintenance task for TB-04 cars. After installation, confirm correct mesh and bearing condition and run a short break-in to seat the parts properly.

Will this help with corner entry and exit?

Yes, a clean-fitting one-way and ring reduces drivetrain lash which can make corner entry and exit feel more consistent, aiding driver confidence.

Is the 51547 compatible with different TB-04 trims?

The set is intended for TB-04 chassis layouts; minor trim or accessory changes may require a check of shaft positions and gear mesh but most standard trims are compatible.

Can I reuse my existing bearings and pinion?

If bearings and the pinion show minimal wear you can reuse them, but worn bearings or a damaged pinion will shorten the life of the new ring; inspect first.

Any tips for run-in after installation?

Run the car at low to moderate speed for a few battery packs, periodically checking mesh and temperature. Recheck screws and bearings after the initial run-in.
