Tamiya Wild Willy 2 WR-02 Aluminium Hi-torque Servo Saver 25T with Aluminium Tie Rod by GPM WW2025TM  [WW2025TM]

Aluminium servo saver for WR-02 steering

This aluminium servo saver and matching tie rod set is an aftermarket upgrade designed for scale RC use on the Wild Willy 2 WR-02 platform. The assembly focuses on protecting the servo from sudden jolts while maintaining steering precision during aggressive driving or technical tuning sessions.

The component replaces stock plastic parts with aluminium parts to increase durability and reduce flex under load. In practice this helps preserve servo centring and provides a more predictable steering response when adjusting trim or steering throws. The 25T reference indicates the compatible servo spline interface intended for higher torque servos.

Installation is typical for WR-02 steering linkages: remove the original saver and link, fit the aluminium saver to the servo horn spline, and secure the tie rod to the steering knuckle and saver arm. Check for correct preload and free movement across the steering arc before final tightening to avoid binding.

For tuning, consider using the aluminium saver when pairing with a hi-torque servo or when seeking firmer feedback for on-track adjustments. The aluminium link reduces unwanted slop, so small trim changes become more effective; however, ensure the chassis and knuckle tolerances are checked to prevent introducing excessive rigidity.
