Aluminum servo arm for TRX4 diff lock

This aluminium servo horn is made for TRAXXAS TRX4 Trail Crawler setups and helps the steering servo actuate the locking differential. Made from 6061 T6 aluminum, the component balances strength and light weight while the built-in spring softens impact forces to limit sudden torque spikes on the servo during technical trail hits.

The kit ships with the small mounting hardware needed for correct spacing and fit. For reliable alignment and minimal slop, follow the installation note: place the 3mm metal washer under the stainless steel round head screw so the screw head does not sit too far from the aluminum collar.

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

How does the spring protect my servo?

The integrated spring absorbs sudden impacts when the diff locks or the axle hits an obstacle, reducing the peak load transferred to the servo gears and motor.

Will this fit stock TRX4 linkages?

It is designed for TRAXXAS TRX4 Trail Crawler layouts and uses the same mounting footprint, but check servo horn spline and screw sizes before final fitment.

Any tips to avoid play after installation?

Fit the 3mm washer beneath the round head screw as advised to prevent a gap between screw head and collar, then torque to the recommended value for your setup.
