Stiffen your chassis with the Tamiya 54390 alloy differential plate

The Tamiya 54390 RC Large Ball Differential Alloy Plate is a straightforward upgrade for FF-03, TA05 ver.II, TRF511, and TRF 501 chassis. It replaces the stock differential plates with a tougher alloy option to reduce component fatigue.

Alloy strength for longer track sessions

These alloy plates offer improved resistance to wear compared to OEM material, helping your differential hold up over repeated runs. The tougher construction helps maintain consistent handling and performance under heavier loads.

Fitment and simple swapover

The pack contains two large ball differential plates so you can replace worn parts during routine service. Compatible with the listed Tamiya chassis models, this set makes maintenance and upgrades quick and predictable.

If the chassis uses the same large ball differential layout as FF-03, it should fit, but check your parts diagram for specific build revisions before ordering.
Standard hobby tools are sufficient: small hex drivers and a screwdriver for diff assembly. Take care with threadlocker on fasteners if you normally use it.
You may notice a slightly firmer response as the alloy reduces flex around the diff area, but gear lash and preload settings remain the primary drivers of diff behavior.
