23T Aluminium Servo Horn for TRX4 Crawling

This set of four aluminium servo horns is an engineered upgrade for TRAXXAS TRX4 Trail Crawler style rigs. Replacing the stock plastic arm gives a tougher, more wear-resistant link between the servo output and steering rod, helping retain steering geometry during heavy use.

Produced from 6061 T6 aluminium, the straight-arm profile reduces unwanted flex when compared to moulded parts while still allowing full suspension travel. The two-position hole layout makes small tie rod length and steering ratio adjustments quick and tool-free, ideal when dialing in crawler handling.

To fit, align the horn on the servo spline, secure with the supplied stainless screws, then select the alternate hole for fine tuning. The set is intended for scale trail crawling and improved steering precision on TRX4 and TRX4-compatible steering 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

Will this fit other crawler platforms?

It is intended for TRX4 spline and mounting standards. Other platforms that use a 23T servo spline may be compatible but verify spline count and clearance first.

How does the dual hole layout affect steering?

Moving the linkage to the alternate hole changes the effective lever arm, allowing you to soften or sharpen steering response without altering servo endpoints.

Are spare screws available?

The kit includes the primary stainless screws required. If you need replacements, use equivalent stainless hardware of the same sizes to maintain fit and finish.
