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

Aluminium 25T Servo Saver for TAMIYA M1025 Hummer

This aluminium hi-torque servo saver is produced by GPM for the TAMIYA M1025 Hummer and is intended as an RC-scale steering protection and damping component. The assembly integrates a 25T interface with a steel tie rod to transfer steering motion while absorbing impact loads away from the servo.

Made for hobby-grade RC use, the unit uses aluminium for the main housing and a steel tie rod for the linkage, providing a stiffer mechanical link compared with stock plastic parts while retaining the sacrificial damping function of a servo saver. It is a component-level replacement intended to improve durability in scale steering assemblies.

Installation notes: confirm your servo uses a 25T spline or compatible horn before fitting, position the tie rod so steering geometry remains correct, and secure fasteners to manufacturer torque recommendations. After installation, verify travel and centring at low throttle and perform a short range test to ensure no binding.

Tuning role: this part helps protect the servo from sudden impacts and can make steering feel more consistent under load, which is useful when adjusting steering throw, servo endpoints, and steering trim for scale handling.
