Designed for racers who want tougher internals, these 3x3mm bushings replace diff balls in ball differentials to create a spool-like action. The swap gives steadier power delivery and helps protect internal parts during hard impacts.
Installing these bushings disables the normal differential action so both wheels receive equal torque. That predictable drive is useful on high-traction surfaces and when you need consistent corner exits.
Under severe load the bushings will slip slightly, acting like a built-in slipper clutch to absorb shock and reduce the chance of stripped gears or broken shafts.
The Tamiya 54424 bushings fit most ball differentials that use 3mm diff balls, making them a handy upgrade for multiple models and spares boxes.
