This replacement servo horn is made for TRAXXAS TRX4 trail crawlers and supplied as model TRX4025TSN. It is precision machined from 6061-T6 aluminium and includes an internal spring to help absorb shocks at the diff-lock servo mounting points.
Fit this horn where a locking differential servo needs a durable, low-mass linkage. The built-in spring reduces instantaneous shock to the servo during impacts and deep articulation, while the alloy construction preserves consistent alignment for hobby-scale drivetrain systems.
Installation notes: seat 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 centre diff-lock servo locations on compatible TRAXXAS chassis fitted to RC trail and crawler rigs.
