Overview and Use

This precision 6061 T6 aluminium adjustable servo horn is intended for TRAXXAS TRX4 Trail Crawler chassis and is supplied as a 7pcs set. Its straight-arm layout gives reliable steering input while the marked adjustment scale makes setting the 20-25mm hole pitch straightforward for a range of servos and linkage arrangements.

Installation mirrors typical aftermarket arms: remove the OEM horn, slide the replacement onto the servo spline, and fasten with the supplied screws. The selectable hole pattern allows quick tuning of steering throw and mechanical advantage without fabricating special links, helping you refine handling on trails and technical sections.

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

Do I need a special servo to use this arm?

No special servo is required; just confirm that your servo spline matches the TRX4-compatible pattern and that the horn's 20-25mm hole range suits your linkage.

How precise are the adjustment marks?

The lasered graduations provide clear reference points to reproduce settings and make small incremental changes to steering geometry.

Will this arm fit on both digital and analogue servos?

Yes, the arm fits servos with the correct spline pattern regardless of electronics type; ensure the hole position and screw length are compatible with your servo output spline.
