Tamiya TT02B Aluminium Hi-torque Servo Horn 25T - TT2B025STM by GPM  [TT2B025STM]

Machined 25T Servo Horn for TT02B

This aftermarket aluminium 25T servo horn and steel tie rod set is made for Tamiya TT02B scale RC models and supplied as a single set. The kit replaces the plastic factory arm with a machined aluminium 25T horn and a steel tie rod to reduce flex at the servo linkage and keep steering inputs more consistent during cornering and setup.

Compatibility requires a matching 25T servo spline and the TT02B steering geometry, so confirm spline engagement and clearance before final assembly. Installation is straightforward: remove the stock horn, seat the 25T aluminium arm onto the servo spline, secure with the original retaining hardware, then attach and adjust the steel tie rod to set neutral toe and steering throw. Avoid over-tightening mounting screws to prevent stripping the servo spline.

In practical tuning this part gives a firmer steering response and cuts play between the servo and steering linkage, which helps when changing steering rates or refining toe and Ackermann on the TT02B platform.
