Precision CNC aluminium horn and spring steel link

This 8-piece upgrade replaces the OEM plastic servo horn and straight steering arm on the TRAXXAS TRX4 Trail Crawler with CNC machined aluminium and spring steel components to deliver improved rigidity and tuning accuracy for demanding crawling setups.

The assembly includes a machined aluminium servo horn and a spring steel tie rod designed for the straight steering arm format, using a 77.5mm centre-to-centre dimension as the reference for toe and steering geometry. The tie rod incorporates a counter-clockwise thread on one end to facilitate swift, reversible length adjustments during fine tuning.

Supplied stainless steel round head screws in multiple lengths and a 3mm lock nut enable secure attachment to stock mounting points, allowing a direct swap-in installation without chassis modification and offering a durable upgrade path from brittle plastic parts.

  • TRAXXAS TRX4 Defender Trail Crawler

What precision benefits does CNC machining provide for this part?

CNC machining ensures consistent bore tolerances and flatness at the servo mounting interface, reducing slop and improving repeatable steering geometry compared to moulded plastic components.

Why combine aluminium horn with a spring steel tie rod?

The aluminium horn provides a rigid servo interface while the spring steel link absorbs minor impacts and resists permanent deformation, delivering a balance of stiffness and resilience for precise control.

Does installation require modification to existing mounts?

No modifications are required; the kit is designed to use the original mounting points with the supplied stainless screws and 3mm lock nut for a reliable, repeatable fit.
