For tuners working on setup, the Tamiya 54399 Rear One Way Pulley 18T swaps in place of the standard pulley to produce crisper handling on demanding layouts. It is a simple upgrade aimed at improving on-track behaviour without complex mods.
Manufactured from aluminium and treated with a hard-coated finish, this pulley resists wear from regular use. The tougher surface helps maintain consistent performance, especially during extended running or club racing sessions.
The component is tailored for the TA06 chassis and installs cleanly using basic hobby tools. It is suitable for enthusiasts who want an effective handling tweak with minimal fuss.
