Kleinn Valve Upgrade

Kleinn Valve Upgrade Kits are designed for enthusiasts who want to push their train horn systems to the next level. These upgrades significantly improve airflow delivery, resulting in louder output, faster response, and a more aggressive tone compared to standard configurations.

Built around the BlastMaster™ and Vortex 6 valve technologies, these kits allow each horn trumpet to receive its own dedicated airflow rather than sharing a single solenoid. This eliminates airflow restrictions and maximizes performance across the entire horn system.

Additional features include oversized airline tubing, upgraded solenoids, and high-flow brass valve components that improve efficiency and durability. These upgrades are especially beneficial for larger systems where airflow demand is critical.

Engineered with universal compatibility (within supported models), these kits integrate seamlessly into existing Kleinn horn setups.

Installation typically involves replacing or adding solenoids and upgrading air lines, making it a straightforward upgrade for most users.

Whether you're upgrading for maximum volume, faster response, or peak performance, these kits deliver a noticeable improvement. Now Available at LEER!
