Precision aluminium horn with spring for lock-diff servos

Engineered for TRAXXAS TRX4 lock-differential servo areas and compatible TRX6 variants, this TRX4025TSN/3 servo horn is machined from 6061-T6 aluminium for a controlled strength-to-weight balance. The integrated spring element provides controlled compliance to mitigate peak shock loads on the servo output during rapid lock or unlock events.

Technical fitment note: the hardware pack contains stainless round head screws and aluminium collars. To remove axial clearance between screw head and collar, position the supplied 3mm metal washer beneath each round head screw prior to final assembly. Proper washer placement improves coupling stiffness and reduces micro-movement at the servo-to-linkage interface.

Packing includes

  • Servo horn - 3pcs
  • Stainless steel round head screws 3*10 - 3pcs
  • Aluminum collar - 3pcs
  • 3mm Metal washer - 3pcs

Compatible Models

  • TRAXXAS-1/10 ELECTRIC 4WD TRX4 DEFENDER TRAIL CRAWLER -82056-4
  • TRAXXAS-1/10 6WD TRX-6 MERCEDES-BENZ G-63 MAG 6X6-88096-4

For hobbyists seeking a precision, impact-tolerant upgrade to the diff-lock servo area, this 6061-T6 aluminium horn with integrated spring offers improved load management and repeatable engagement when installed with the supplied washers.

The spring allows limited angular compliance, absorbing transient shocks and lowering peak torque transmitted to the servo, which improves longevity under repeated lock/unlock cycles.
Yes, the horn is intended as an aftermarket direct-fit for the TRX4 lock-diff servo area, but users should confirm mounting dimensions and servo spline compatibility before installation.
Use the supplied stainless screws and collars, place the 3mm metal washer under each screw head to remove play, and torque screws to a controlled value to avoid stripping the collar bore.
6061-T6 offers a combination of machinability, tensile strength, and corrosion resistance suitable for scale aluminium parts where weight and impact resistance must be balanced.
