Refine Your TRF419 with the Tamiya 51566 37T Case

The Tamiya 51566 Gear Differential Case is engineered for the TRF419 on-road 4WD chassis. The 37-tooth configuration allows a larger oil reservoir than older cases, which supports higher output motor setups and helps drivers dial in consistent diff behaviour around the circuit.

Can I use this case on a modified gearbox?

If your gearbox follows TRF419 dimensions it will usually accept this case, but custom modifications may need shimming or spacing checks before installation.

Does the 37T affect diff durability?

With increased oil capacity the diff runs cooler under load, which can reduce wear when paired with suitable maintenance and correct oil choice.

Is any special tooling required to fit it?

Basic RC hand tools and patience are sufficient for most experienced builders. Check manual torque specs and inspect seals during assembly.

Will changing diff oil still tune handling?

Yes, oil viscosity remains a primary tuning tool. The larger capacity gives a broader tuning window for fine adjustments to traction and corner entry.
