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

25T Aluminium Servo Saver Upgrade for TAMIYA M1025 Hummer

This aluminium hi-torque servo saver is an aftermarket steering protection unit for the TAMIYA M1025 Hummer. It couples a 25T spline interface with a steel tie rod so steering inputs are transferred while impact energy is absorbed away from the servo.

Designed for hobby-grade applications, the aluminium housing paired with a steel tie rod gives a stronger mechanical linkage than stock plastic parts while preserving the sacrificial damping action of a servo saver. Use it as a replacement part to improve scale steering durability.

Installation notes: confirm a 25T spline match on your servo horn before fitting, arrange the tie rod to keep steering geometry correct, and fasten components to manufacturer torque guidances. After assembly, check travel and centring and perform a slow-range test to ensure smooth operation.

Tuning use: the saver reduces direct shock to the servo and can make steering feel more predictable under load, helping when trimming endpoints, steering travel, and centring for realistic steering behaviour.
