Servo horn for TRX4 differential lock

This aluminium servo horn is specified for TRAXXAS TRX4 Trail Crawler layouts to assist the servo in locking the differential. Fabricated from 6061 T6 aluminium, it offers a strong yet light option and the built-in spring cushions sudden shocks so the servo sees fewer peak loads during rough manoeuvres.

The assembly comes with the small fasteners needed for mounting and correct spacing. To maintain alignment and reduce play, fit the 3mm metal washer beneath the stainless steel round head screw so the screw head does not sit too far from the aluminium collar, as noted in the installation guidance.

Packing includes

  • Stainless Steel Round Head Screws 3*10 - 1pcs
  • Aluminum Collar - 1pcs
  • 3mm Metal Washer - 1pcs

This item is compatible with

  • TRAXXAS TRX4 Defender Trail Crawler

Does this reduce servo strain on rock sections?

Yes, the spring helps absorb impact energy when the diff locks or an axle hits an obstacle, reducing instantaneous torque on the servo.

Is additional machining required to fit?

No extra machining is normally required; use the supplied hardware and check spline compatibility with your servo before full installation.

How should I check for endplay?

With the horn fitted, cycle the diff and visually confirm there is minimal axial movement; the washer under the screw helps eliminate unwanted gap.
