TAMIYA BBX BB-01 Medium Carbon Steel Spur Gear by GPM BBX086TS  [BBX086TS]

Medium carbon steel 86T spur gear

This 86-tooth spur gear is an RC-scale replacement part produced by GPM for the TAMIYA BBX BB-01 platform. Constructed from medium carbon steel, the tooth profile is intended to offer greater wear resistance compared with the stock nylon spur gear while fitting the BB-01 gear stack and mesh requirements.

Use this spur gear when you need a metal alternative for routine tuning or durability upgrades; it is intended for model-level use only and does not imply any real-vehicle application. Check gear mesh and pinion alignment during installation to avoid premature wear on mating parts and bearings.
