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

25T Aluminium Servo Saver for TAMIYA M1025 Hummer

This aluminium hi-torque servo saver is designed for use on the TAMIYA M1025 Hummer as a scale steering protection and damping component. The unit features a 25T spline interface and a steel tie rod that transmits steering input while deflecting shock loads away from the servo.

Built for hobby-grade running, the assembly uses an aluminium housing and a steel tie rod to give a firmer mechanical connection than stock plastic parts, while still functioning as a sacrificial damping element to protect the servo. It is intended as a direct component replacement to improve longevity in scale steering linkages.

Installation notes: check that your servo horn or adapter matches a 25T spline before fitting, set the tie rod position to preserve steering geometry, and tighten fasteners to recommended torque. After fitment, confirm travel and centring with the vehicle stationary and perform a short low-speed test to check for binding.

Tuning role: the servo saver helps shield the servo from sudden impacts and can stabilise steering behaviour under load, aiding adjustments to steering endpoints, throw, and trim for more consistent scale handling.
