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.
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.
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.
