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

Aluminium Hi-torque Servo Saver for WR-02

This aluminium hi-torque servo saver is an aftermarket steerage component produced for the Tamiya Wild Willy 2 WR-02 chassis, supplied as a single set by GPM WW2025STM. Built around a machined aluminium housing and a steel tie rod, it replaces the stock saver to offer a rigid, durable steering interface intended for RC-scale use on the WR-02 platform.

Functionally the unit separates steering shocks from the servo while preserving mechanical centring, acting as a sacrificial interface that reduces stress on the servo during impacts. The 25T designation in the product name identifies the servo spline interface used by this part and the included steel tie rod provides a direct connection for steering link adjustments.

Installation is straightforward for hobbyists familiar with the WR-02 steering assembly: remove the original saver, fit the aluminium body onto the spline, secure the assembly and reattach the tie rod. After installation, verify spline engagement and steering centring, then fine-tune tie rod length to correct wheel alignment and steering throw as needed.

Tuning notes: the stiffer aluminium body and steel tie rod lower flex in the steering linkage compared with softer stock savers, which can improve steering precision at the cost of transmitting more feedback to the servo; adjust steering trim and end points accordingly when switching to this unit.
