This GPM replacement part is an RC-scale servo horn intended for use with TRAXXAS TRX4 based trail crawlers, supplied as model TRX4025TSN by GPM. It is machined from 6061-T6 aluminium and includes an integrated spring to help absorb shocks at the diff-lock servo mounting points.
Use this horn where a locking-differential servo needs a durable, low-weight linkage. The built-in spring reduces direct shock to the servo during impacts and tight articulation, and the alloy construction provides consistent fitment for hobby-scale drivetrain setups.
Installation notes: fit the aluminium collar and secure with the supplied round-head screw, placing the 3mm metal washer beneath the screw head to remove excess gap between the screw and collar. This part is intended for front, rear, or center diff-lock servo locations on compatible TRAXXAS chassis fitted to RC trail and crawler rigs.
