This upgrade set is aimed at the Tamiya GF-01 chassis and swaps out factory plastic steering components for a 25T aluminium servo saver and aluminium tie rods to improve steering stiffness and reduce play on scale and crawler models.
Installation involves taking off the stock saver, fitting the aluminium saver to the servo spline, and replacing the tie rods while setting their lengths for neutral tracking. Use common hand tools and confirm correct thread engagement during assembly.
Tuning pointer: firmer aluminium linkages increase feedback to the servo, so check spline engagement and adjust servo end points if the servo load rises. This kit provides mechanical improvement to steering precision rather than electronic enhancements.
