Upgrade or repair the steering linkage of your desert truck with this Composite Servo Arm with Metal Inserts. Designed for the Losi Baja Rey and Rock Rey, this servo horn solves the number one problem with stock Ready-to-Run (RTR) steering systems: stripped splines.
Unlike a standard all-plastic horn that can easily strip smooth under the high torque of rock racing, this unit features a Metal Spline Insert.
Key Features
-
Metal Spline Inserts: The critical connection point to the servo is made of metal, virtually eliminating the risk of stripping the "teeth" inside the horn during a crash.
-
Multi-Brand Compatibility: Includes inserts to fit the two most common servo spline counts:
-
23T Insert: Fits Spektrum, Sanwa, Airtronics, and KO Propo servos (Standard for Losi RTRs).
-
25T Insert: Fits Futaba, Savox, and Power HD servos (Standard for aftermarket upgrades).
-
-
Durable Composite Body: The arm itself is molded from Losi’s heavy-duty black plastic, designed to withstand the vibration and heat of off-road racing.
-
Direct Fit: Designed with the correct length and offset for the Baja Rey steering bellcrank geometry, ensuring full steering throw without hitting the chassis.
