Futaba FUEBS3373 Servo Case Set for BLS154 BLS174HV BLS174SV  [FUEBS3373]

Servo case set overview

This Futaba FUEBS3373 servo case set is an RC-scale replacement housing designed for use with Futaba BLS154, BLS174HV and BLS174SV servos. The set focuses on providing a direct-fit enclosure that accepts the internal components of the listed servo models and preserves factory mounting points for straightforward installation.

Designed as a component-level accessory, the case set plays a role in repair and chassis tuning by allowing you to swap damaged housings or test servo internals without replacing the entire unit. It is intended for model applications only and does not imply any real-vehicle use.

Installation notes: the case set requires careful transfer of the servo’s internal gear train and electronics into the replacement shell, checking alignment and engagement before final fastening. Maintain original screw positions and verify horn alignment and travel during reassembly to avoid binding or altered neutral position.
