Compatible with HPI Bullet 3.0 MT/ST Servo Saver Horn, Gunmetal - BUL-18007-GU by Jazrider  [BUL-18007-GU]

Upgrade Horn for Bullet 3.0 MT and ST

This gunmetal servo saver horn is an aftermarket replacement built for HPI Bullet vehicles where a tougher servo-saver interface is preferred. Constructed in gunmetal alloy as noted, it is intended for use with Bullet 3.0 MT and ST platforms to protect servo linkages and provide smoother steering control in nitro off-road conditions.

Fit and role: it replaces the standard saver horn that connects the servo output to the steering linkage, transmitting steering inputs while allowing controlled give under impact. The metal construction gives a more rigid contact surface compared with typical plastics, helping keep steering geometry stable during aggressive driving.

Installation notes: mount at the servo output using the vehicle's original saver attachment points; confirm the horn aligns with your servo arm and linkage, set steering to neutral before tightening, and use original screws if they match. Verify servo centering and travel after installation to ensure correct operation.

Tuning and maintenance: use this horn to adjust servo feel together with any available saver spring or damper choices, inspect for wear on mating surfaces, and replace if deformation appears to prevent binding or inconsistent steering response.
