Tamiya F1 1/4" Axle Adapter Bearings Set, for TRF104 F104

Converts your Tamiya F1 from its stock metric bearings to easily accept 1/4" rear axle sets. Allows you to install more tuning options in the way of industry standard 1/4" axle ball diffs, spools and gear diffs used on most other F1 kits.
Adapts any Tamiya F1 that uses normal 6x10mm axle bearings such as the F104, TRF104, TRF103, Group C cars, ETC.

When you install the 1/4" diff, do not forget to also purchase the left side F1 wheel hub such as Exotek #R4021.
