HPI Bullet Servo Saver Horn for Bullet 3.0 MT and ST - BUL-18007-GU by Jazrider  [BUL-18007-GU]

Gunmetal Servo Saver Horn for HPI Bullet

This gunmetal alloy servo saver horn is an RC-scale replacement intended for HPI Bullet chassis where a stronger saver interface is required. The component is produced in gunmetal alloy and is built to work with Bullet 3.0 MT and ST platforms, helping protect servo linkages and smooth steering inputs during nitro off-road runs.

Fit and role: the horn replaces the stock saver arm that links the servo output to the steering linkage, passing steering commands while allowing controlled give on impact. As a metal upgrade it offers a firmer contact surface versus standard plastic, which can help retain steering geometry under heavy use.

Installation notes: fit at the servo output using the vehicle's existing saver mounting points and hardware; verify alignment with your servo arm and linkage, centre the steering before tightening, and reuse the original screws where they match the chassis threads. Check travel and servo centering after installation.

Tuning and maintenance: pair the horn with the appropriate spring or damper setting inside the saver if your assembly allows it, inspect mating faces periodically for wear, and replace the horn if you detect deformation that could cause binding or erratic steering.
