Tamiya M1025 Hummer Aluminium Hi-Torque Servo Saver 25T with Tie Rod HM1025TM by GPM  [HM1025TM]

Robust steering saver for the M1025 Hummer

This aftermarket servo saver and aluminium tie rod kit is a scale replacement for the Tamiya M1025 Hummer, specified as a hi-torque 25T style and finished in aluminium. The pack is designed to protect the steering servo by allowing a controlled give in the linkage and to reduce flex compared with standard plastic rods.

Role and fit: made for the M1025 Hummer platform that uses a 25T servo spline, the item is a tuning and durability upgrade rather than an electronic enhancement. It helps deliver steadier steering feedback and a longer-lasting linkage solution than many factory plastic parts.

Mounting notes: the saver substitutes the stock servo saver assembly and the aluminium tie rod replaces the plastic steering rod. During fitting ensure proper spline alignment and secure attachment to the servo arm at the original mount points. Once installed, set steering centre and check travel to avoid binding at extremes.

Adjusting and care: swapping to a metal tie rod reduces play and sharpens steering response while the saver still cushions impacts to protect the servo. Regularly check fasteners and spline wear, and reassess steering geometry after any suspension or steering modifications.
