Futaba FUAS4145 Direct-Fit Servo Shells for S9172SV S9551 S9570SV S9571SV  [FUAS4145]

Product Summary

This Futaba FUAS4145 servo case set offers replacement housings tailored for the S9172SV, S9551, S9570SV and S9571SV RC-scale servos. The kit is aimed at hobbyists and technicians who need to replace cracked or worn casings during routine maintenance or field repairs.

The shells are designed for direct installation with the listed Futaba models so that internal gears, motors, and electronics can be transferred without modification. Servos serviced this way retain their internal components and can preserve existing calibration once reassembled.

Using replacement cases during setup and tuning helps maintain consistent output shaft alignment and mounting flange positions, supporting repeatable steering and control characteristics in model applications. This accessory is not intended for use on full-size vehicles.
