Universal Shaft BB Set compatible with TRF421/TRF421X - Tamiya 51762  [51762]

Drive shaft bearing replacement kit

This spare parts set provides the ball-bearing components and drive shafts used with Tamiya TRF421 and TRF421X touring car platforms. The kit supplies the bearings and retaining hardware needed to replace worn universal shaft internals or to upgrade factory-standard parts on TRF421-series models.

The contents are intended for RC-scale applications only and match the layout used on TRF421 (Item 42384) and TRF421X (Item 42391). Use the parts together with the listed complementary items when applying the set to a TRF421 chassis to ensure correct fit and function.

When replacing or upgrading universal shaft assemblies on TRF421-series cars, pair this set with Items 51760, 51761, 51763 and 51764 as noted for TRF421 installations to maintain intended alignment and bearing support.
