TAMIYA BBX BB-01 Front Freewheel Axle 4140 Medium Carbon Steel BBX021/PIN by GPM  [BBX021/PIN]

Front freewheel axle replacement

This axle set is a direct RC-scale replacement for the front freewheel on the TAMIYA BBX BB-01 platform. Made from 4140 medium carbon steel, the paired axles are intended to reduce rotating mass and alter acceleration response while preserving the existing drivetrain layout.

Supplied as a two-piece set, the components suit hobbyists tuning 1/10 scale electric models who want a predictable change in front-end inertia. Always verify fitment against the compatible model list before fitting the axles to your chassis.
