Technical servo horn for TRX4 locking differential

This 6061 T6 aluminium servo horn is supplied for TRAXXAS TRX4 Trail Crawler installations to assist the servo when actuating the locking differential. The alloy construction provides a balance of strength and minimal weight while the integrated spring cushions shock inputs, reducing transient load peaks on the servo during off-road impacts.

The kit includes the small mounting hardware required to achieve correct spacing and secure attachment. During assembly place the 3mm metal washer beneath the stainless steel round head screw so the screw head does not sit at an excessive distance from the aluminium collar, preserving alignment and limiting play.

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

What is the main benefit of this horn when used with TRX4 diffs?

The spring-loaded interface reduces sudden torque spikes transmitted to the servo during diff engagement or impact events, improving longevity of servo components.

Are the supplied parts enough for a standard install?

Yes, the package contains the specified stainless steel screw, aluminium collar and 3mm washer required for proper mounting and spacing on typical TRX4 setups.

How do I ensure minimal endplay after fitting?

Fit the 3mm washer under the round head screw as instructed, verify collar seating and then test differential operation to confirm negligible axial movement.
