TAMIYA M1025 Hummer Aluminium Hi-torque 25T Servo Saver Upgrade with Steel Tie Rod HM1025STM by GPM  [HM1025STM]

Aluminium 25T Servo Saver Upgrade for TAMIYA M1025 Hummer

This aluminium hi-torque servo saver is offered as an upgrade for the TAMIYA M1025 Hummer steering assembly. It incorporates a 25T spline interface and a steel tie rod to transmit steering motion while diverting impact forces away from the servo geartrain.

Made for hobby use, the aluminium body and steel tie rod deliver a firmer link than OEM plastic components while retaining the sacrificial damping benefit of a servo saver. It serves as a component replacement to increase longevity in scale steering setups.

Installation notes: ensure your servo horn accepts a 25T spline before installation, align the tie rod to maintain correct steering geometry, and torque fasteners to recommended values. After fitting, confirm centring and endpoints at low speed and carry out a short test run to check for binding.

Tuning role: by reducing shock transmission to the servo, this part can stabilise steering feel and help when setting trim, travel limits, and centring for more predictable scale handling.
