HornBlasters King 3 Train Horn Manifold
THE FOUNDATION OF THE ICONIC KING 3
The King 3 Manifold is used as the base for our King 3 Train Horn. It’s made from die-cast aluminum and built to handle real-world abuse. Whether you're replacing a damaged manifold or piecing together a 3-chime locomotive horn, this gives you the solid base you need. It's also compatible with other 3-chime train horns that use a similar bolt pattern, including Nathan Airchime K-bells.
- Die-Cast Aluminum Construction: Built from durable die-cast aluminum for long-term use. Strong, lightweight, and resistant to corrosion.
- Compatible with Nathan Airchime K-Bells: Designed to fit HornBlasters King 3 bells and other 3-chime setups with matching spacing—including genuine K-series Nathan Airchime bells.
- Reliable for Custom Installs or Replacements: Whether you're building a horn from scratch or replacing an old manifold, this gives you a dependable platform to work from.
If you're serious about building a real locomotive-style horn, this manifold gives you the strength, fitment, and flexibility to make it happen.
**PLEASE NOTE: This listing is for the manifold only. Bells, mounting hardware, and air systems are sold separately.**
