Futaba FUAS4145 Servo Housing Kit for S9172SV S9551 S9570SV S9571SV  [FUAS4145]

What the Case Set Provides

The Futaba FUAS4145 case set includes replacement shells designed for RC servos with model numbers S9172SV, S9551, S9570SV and S9571SV. These housings are intended to be swapped onto the listed servos during repair work or routine servicing.

As direct-fit replacements for the specified Futaba units, the shells let technicians transfer internal gear trains, motors and electronics without modifying the original components. Transferring internals into the new casing preserves the servo's original calibration while restoring external protection.

When setting up or tuning a model, fresh casings can help keep output shaft alignment and mounting points consistent, which aids repeatable control response. This item is an accessory for scale models and is not suitable for full-size vehicle use.
