Overview

This is an RC-scale aluminum adjustable servo horn designed for use on TRAXXAS TRX4 Trail Crawler chassis, supplied as a 7pcs set by GPM. The straight-arm layout and 6061 T6 aluminum construction focus on durability and predictable steering input while remaining a dedicated model-scale part for trail crawling setups. Marked adjustment graduations make it straightforward to set the 20–25mm hole pitch to suit different servo splines and linkage geometries.

Installation is typical for aftermarket servo arms: remove the stock horn, fit the replacement to the servo spline, and secure with the provided screws. The adjustable hole pattern supports minor tuning of steering throw and linkage leverage without fabricating extra parts, letting you tune steering sensitivity and endpoint behavior on the model.

Packing includes

  • Servo Arm - 2pcs
  • Stainless Steel Round Head Screw 2.5x10 - 3pcs
  • Stainless Steel Round Head Screw 3x14 - 1pc
  • Stainless Steel Round Head Screw 3x8 - 1pc

What servo spline sizes does this accept?

The horn fits typical TRX4-compatible servo splines; confirm your servo spline matches the stock TRX4 horn before fitting.

How do I use the adjustable hole pitch?

Select the hole that aligns the linkage with neutral steering, then secure with the supplied screws; the lasered scale helps repeat settings.

Are the included screws sufficient to mount the horn?

Yes, the set supplies a selection of stainless steel round head screws to match common TRX4 servo mounting requirements.
