TRX4 Scale Spring-Loaded Servo Horn 6061-T6 TRX4025TSN/3 by GPM  [TRX4025TSN/3]

Spring-loaded aluminium horn for TRX4 lock-diff servos

This is an aftermarket servo horn made to suit TRAXXAS TRX4 lock-differential servo areas and certain TRX6 variants, supplied as TRX4025TSN/3. Manufactured from 6061-T6 aluminium, the unit incorporates an internal spring to cushion shock and limit force transferred to the servo during abrupt lock or unlock cycles.

Fitting advice: the package includes stainless round head screws and alloy collars; to remove excess gap between each screw head and its collar, place the provided 3mm metal washer beneath the screw head. Doing so reduces play and ensures a secure coupling from the servo output to the diff-lock linkage.

For trail enthusiasts running a TRX4 diff-lock, this 6061-T6 aluminium horn with an integrated spring is a direct-fit aftermarket choice; follow the washer placement step to maintain tight, reliable engagement.
