This servo saver horn is an RC-scale replacement part intended for HPI Bullet chassis where a stronger servo saver interface is desired. Manufactured in gunmetal alloy as indicated by the product name, the component is designed to work with the Bullet 3.0 MT and ST platforms and focuses on protecting the servo linkages and smoothing steering inputs under nitro off-road conditions.
Fit and role: the part replaces the standard saver horn that connects the servo output to the steering linkage, transferring steering inputs while allowing controlled give under impact. As an upgraded material option, the gunmetal alloy provides a stiffer contact surface compared with typical plastics, which can help maintain consistent steering geometry during aggressive runs.
Installation notes: this RC accessory installs at the servo output and uses the vehicle's existing saver mounting points and hardware; check fit with your existing servo arm and linkage, align the horn to neutral steering, and secure using the original screws or hardware sized for the chassis. Test steering travel and servo centering before full use.
Tuning and maintenance: use the horn to fine-tune servo feel by pairing it with the appropriate spring or damper settings in the servo saver assembly if applicable, inspect the mating surfaces regularly for wear, and replace if deformation is evident to avoid imprecise steering or binding.
