Model 6890: Ultra BlastMaster™ Upgrade Kit for Demon 730 Train Horns

Engineered Exclusively for Model 730 Demon™ Train Horns

Experience the Demon 730 Horns in all their glory!  The Ultra BlastMaster™ (6890) re-engineers the 730 horns to deliver a 30% decibel increase through optimized airflow and extreme output.  It’s a simple law of physics: more air equals more power. The 6890 pushes the Demon horns to their limit by ditching the standard 3/8” lines in favor of a massive, dedicated 1/2” airline and high-flow brass solenoid for each individual horn. The result is a shocking twist on a classic; delivering devastating, soul-shaking decibel levels that command attention across city blocks. Overwhelm the senses and dominate the streets with the absolute peak of train horn intensity, because when it comes to the ultimate set up, “TOO LOUD” is just right.

Why Upgrade to Ultra BlastMaster™?

  • Triple-Valve Power: This kit provides everything required to add two VX6003 solenoid valves to your existing setup. By dedicating a high-flow valve to every single trumpet, not only is the blast next level, but you ensure instant simultaneous actuation while eliminating airflow bottlenecks entirely.
  • 30% More Output: We don't just add valves; we open the floodgates. Unleash maximum output with dedicated 1/2" high-flow airline fed to every horn solenoid, increasing the volume of air reaching the horn drivers simultaneously. The Ultra BlastMaster™ 6890 forces your Demon™ horns over the edge, resulting in a deeper, louder, and more aggressive blast.
  • Professional-Grade Components: Includes premium high-pressure fittings and our legendary Vortex 6 (VX6003) brass solenoids, 1 on each horn, to maximize air delivery ensuring your system handles the increased demand without breaking a sweat.
  • Extreme Output Warning: This isn't a subtle upgrade. This is a total transformation. Prepare your eardrums; they’re screwed.

⚠️ IMPORTANT FITMENT NOTES:

This kit is engineered specifically for Model 730 Demon™ horns.

(For the Model 230 Beast™ horns, please use Blastmaster Upgrade Model 6885).

This warranty encompasses a promise that the product you have purchased will perform as expected under normal use conditions and will not suffer from flaws in materials or craftsmanship. However, it is important to note that this warranty does not cover any damage that results from abusive use, operation that is not in line with the product’s intended purpose, or harm resulting from exposure to harsh environmental conditions. In the event that a product is found to be defective within the warranty period following a thorough inspection, Kleinn Automotive Accessories reserves the right to either repair or replace the defective item at no additional charge to the purchaser. It is our goal to ensure that our products meet the high standards that our customers expect, but we also want to clarify that Kleinn is not responsible for covering any costs related to the installation of our products, nor are we liable for any loss or damage that may occur as a result of the repair or replacement process of any product under warranty.

Detailed Warranty Return Procedure:

Should you need to initiate a return under the warranty, we have a straightforward process designed to make it as convenient as possible for our valued customers. To start, you will need to email a copy of your sales receipt, which must be dated within the past year for standard warranty claims or within the past two years for claims under the extended warranty for the 6450 Compressors and 730 Horns. This email should be directed to our Warranty Manager and include your full name, email address, telephone number, and a concise description of the problem you are experiencing.

Upon receipt of your email, a dedicated representative from Kleinn Automotive Accessories will reach out to you directly. Our first step will always be to attempt to resolve the issue through technical support, aiming to provide a quick and effective solution. If the problem cannot be addressed remotely, our representative will issue a Return Authorization number. This number is crucial as it will identify your return throughout the inspection process. You are then required to send the product back to Kleinn Automotive Accessories for a comprehensive physical inspection.

Upon inspection, if the product is determined to be defective due to issues in workmanship or materials, Kleinn will undertake to either repair or replace the product at our discretion. We are committed to ensuring that our customers receive products that meet our high-quality standards, and we will make every effort to resolve warranty claims to your satisfaction. However, if the inspection reveals that the product does not have a material defect, we will return the unit to the customer. In such cases, the shipping costs for the return will be the responsibility of the customer.
