23T Aluminum Servo Arm for TRX4 Steering

This four-piece aluminum servo horn is an RC-scale upgrade for TRAXXAS TRX4 Trail Crawler builds. It replaces the factory plastic arm to give a firmer, wear-resistant interface between the servo output spline and the steering linkage, helping keep steering geometry consistent under load.

Machined from 6061 T6 aluminum, the straight-arm profile reduces flex compared with molded parts while remaining compact for tight suspension travel. Dual-position holes let you tweak tie rod length and steering sensitivity without changing other linkage hardware, useful when adjusting toe or steering ratio for technical lines.

Installation is simple: align the horn to the servo spline, fasten with the supplied stainless steel screws, and use the alternate hole to fine-tune linkage position. The set is aimed at scale trail crawling and improved steering response on TRX4 chassis and TRX4-compatible setups.

Packing includes

  • Stainless Steel Round Head Screws 3x14 - 1pcs
  • Stainless Steel Flat Head Screws 3x8 - 1pcs
  • Stainless Steel Cap Head Screws 2.5x6 - 1pcs

Which servos and splines are compatible with this horn?

The horn fits standard 23T servo splines used in many scale servos. Check your servo spline count before fitting to ensure correct engagement.

Will this require longer or shorter linkages?

The dual-position mounting holes provide minor adjustments to tie rod length. Most installs use existing linkage lengths, but you can fine-tune toe and steering ratio by switching holes.

What tools do I need for installation?

No specialty tools are supplied. A set of hex drivers or small screwdrivers suitable for the included stainless screws is all that is needed.
