Servo arm (for Lockable Differential)

Traxxas 5669 - Shift Servo Horn with Spring for Locking Differential

The Traxxas 5669 is a shift servo horn with a built-in spring and mounting hardware. The spring provides a degree of flex under load, helping protect the servo and drivetrain when operating the locking differential. It is designed for the Summit and several TRX-4 and TRX-6 models equipped with a locking differential, making it a suitable replacement or spare part for the original component.
