Manufactured from 6061 T6 aluminium, this GPM servo horn is intended to refine locking differential behaviour on the Traxxas TRX4 while maintaining a favourable strength to weight ratio. The captive spring element provides controlled compliance to reduce shock loads transmitted to the servo gearbox.
For consistent mechanical engagement, position the 3mm metal washer under the stainless steel round head screw so the screw head fully engages the aluminium collar. This prevents axial clearance and preserves precise linkage alignment under load.
