TRAXXAS TRX4 Aluminium Servo Horn & Steering Link Set - TRX416025 by GPM  [TRX416025]

Aluminium steering parts for TRX4 crawling

This aftermarket aluminium servo horn and steering link kit is built for TRAXXAS TRX4 Trail Crawler owners and sold under model TRX416025. The 8 piece set replaces the original plastic horn and link to reduce flex and sharpen steering inputs for scale trail use.

The steering link includes a counter-clockwise threaded tie rod so length can be adjusted without rotating ball end seating, which simplifies toe and steering bias corrections. The centre-to-centre measurement between ball ends is 77.5mm and is useful when matching or comparing components.

What's included: the kit comes with stainless steel mounting screws and a lock nut, and the primary components are aluminium to cut wear versus stock plastic parts. The design suits scale trail crawlers using a straight steering arm arrangement who want a firmer steering feel.

Fitting and tuning tips: swap the aluminium horn for the plastic original using the supplied fasteners, ensure the servo spline is aligned before final torque, and fine tune length with the CCW tie rod while checking centring and travel. This direct upgrade addresses plastic arm weakness and gives steadier steering during technical crawling.
