Use these shafts with a range of Tamiya Mini 4WD platforms, including Mini 4WD Pro, MS, Super TZ-X, Super TZ, Super FM, FM, Super 1, Zero, Type 5, Type 4, and Type 2. Their broad compatibility makes them suitable for many common model builds and upgrades.

On-track benefits

With a fluorine coating that lowers surface friction, these shafts promote smoother gear rotation and can help reduce rolling resistance. That smoother motion may translate to steadier runs and fewer pit-side adjustments during race days.
