Supplied as model TRX4025TSN, this replacement horn is intended for TRAXXAS TRX4 trail and crawler models. The component is CNC machined from 6061-T6 aluminium and includes an internal spring to absorb shock at the diff-lock servo mounting interface.
Use it where a locking differential servo requires a strong but light linkage. The spring reduces sudden shock to the servo during impacts and extreme articulation, and the alloy construction ensures consistent fit and alignment in scale drivetrain layouts.
Installation notes: locate and seat the aluminium collar, then secure with the supplied round-head screw leaving the 3mm metal washer under the screw head to remove play between the screw and collar. This part is suitable for front, rear, or centre diff-lock servo positions on compatible TRAXXAS chassis used in trail and crawler setups.
