This replacement horn is an alloy servo saver manufactured for HPI Bullet scale models. It links the servo horn to the steering linkage and absorbs sudden steering shocks or impacts to lower gear stress inside the servo.
The orange-anodized alloy delivers a harder-wearing, firmer contact surface than the stock plastic item while remaining sufficiently light for scale installations. It is designed as a direct replacement for Bullet 3.0 MT and ST nitro chassis when the original saver shows wear or when a tighter steering feel is required.
To fit: remove the servo horn fasteners, install this alloy saver, verify the servo's centre position and travel limits, then secure to the recommended torque. Minor linkage trimming or adjustment can be needed to re-establish neutral steering. Use it during routine service or when refining steering behaviour.
