TAMIYA TT02B Lightweight Aluminium 25T Servo Horn with Tie Rod - TT2B025TM by GPM  [TT2B025TM]

Aluminium 25T steering horn for TT02B models

This aluminium 25T servo horn together with an aluminium tie rod is supplied as an aftermarket option for the TAMIYA TT02B chassis, model TT2B025TM. It replaces the factory plastic arm to create a stiffer connection from the servo output to the steering linkage, improving steering consistency when the model is under load.

Fitment is uncomplicated but requires attention: confirm the servo has a 25T spline, centre the servo before fitting the horn, and tighten with the original mounting screw(s). Take care not to over-torque and check thread engagement to avoid damaging the spline or screws. Intended only for radio-controlled model use.

From a tuning perspective the aluminium horn and tie rod reduce steering compliance and provide a more direct mechanical feel when used with a stronger servo. Always verify steering throw and clearances after installation to ensure unobstructed movement.
