Tamiya Wild Willy 2 WR-02 Aluminium Hi-Torque Servo Saver 25T with Steel Tie Rod WW2025STM by GPM  [WW2025STM]

Machined Aluminium Hi-Torque Saver for WR-02

This machined aluminium hi-torque servo saver is an aftermarket steering component made for the Tamiya Wild Willy 2 WR-02 chassis and supplied as a single set labelled WW2025STM. The unit pairs a machined aluminium housing with a hardened steel tie rod to replace the softer stock saver and provide a firmer steering interface suitable for scale RC running.

The saver functions by isolating shock loads from the servo while keeping mechanical centring. The 25T note refers to the spline interface, and the included steel tie rod gives a direct, adjustable link to the steering bellcrank for quick alignment changes.

Installation is straightforward for anyone familiar with WR-02 steering assemblies: remove the factory saver, fit the aluminium body to the servo spline, secure the unit and reconnect the tie rod. After fitting, check spline engagement and centring, then trim tie rod length to dial in toe and steering throw.

Tuning tip: the stiffer aluminium body and steel tie rod reduce flex in the linkage compared with the stock saver, which sharpens steering response but can pass more feedback to the servo; adjust trim and end points after the swap to protect the servo and achieve the desired steering feel.
