Frequently Asked Questions

Micheal's 2018 Ford F350 Lariat features a dual train horn installation, providing twice the sound output and commanding presence. This setup uses multiple horn sets for maximum impact while maintaining the luxury features of the Lariat trim level.

Dual Shocker XL systems or a combination of Shocker XL with Nathan K3 horns work excellently for dual installations. This configuration requires larger air systems, typically 10+ gallon tanks with powerful compressors to support both horn sets simultaneously.

Dual horn systems require substantially larger air capacity, typically 10-15 gallon tanks with XD4000 or dual compressor setups. Operating pressure remains at 150 PSI, but recovery times and sustained honk capabilities are significantly enhanced with the larger air storage.

The 2018 F350 Lariat combines luxury features with heavy-duty capability, providing the robust frame construction needed for dual horn systems while maintaining comfort and premium amenities. The truck's electrical system easily supports the additional power requirements.

Dual installations require careful planning for mounting locations, increased electrical capacity, and larger air system components. Professional installation is recommended to ensure proper weight distribution, secure mounting, and optimal horn placement for maximum sound projection.
