ENGINEERED EXCLUSIVELY FOR BEAST™ MODEL 230 HORNS
Unleash the true acoustic boundaries of your air setup with the premium Kleinn Model 6885 Ultra BlastMaster™ Upgrade Kit. While standard multi-bell setups face structural flow caps, this high-performance engineering package entirely resets the baseline for extreme pneumatic delivery. By completely re-engineering the internal airflow mechanics of your existing Beast™ 230 assembly, this kit forces the maximum volume of air directly into the trumpets simultaneously. The physics are simple: more air volume equals more acoustic power, resulting in devastating, bone-rattling decibel output that commands total highway respect.
MAXIMUM FLOW VOLUME AND DYNAMIC INTENSITY
The Ultra BlastMaster™ system replaces your restrictive baseline air delivery layout to open the performance floodgates. By transitioning your principal tank supply line to a massive 1/2" high-pressure feed run, this kit completely ditches standard restrictive 1/4" lines. This massive jump in cubic feet per minute (CFM) allows the drivers to hit peak operational volume immediately, transforming your system into a deeper, noticeably louder, and far more aggressive train horn layout. When it comes to the ultimate vehicle configuration, "too loud" is just right.
THE VERDICT: The absolute peak of train horn intensity. The Model 6885 re-engineers your existing Beast™ setup into a multi-valve powerhouse, delivering the massive airflow scaling and instantaneous burst speeds required to rule the road.
This specialized performance upgrade kit is engineered specifically for the Model 230 Beast™ Train Horn architecture. (For systems running the Model 730 Demon™ horns, please utilize BlastMaster™ Upgrade Model 6890).
Model 6885 is the official upgrade for the following Kleinn systems:
🔴 PRO TIP: Balance your upgraded pneumatic speed with clean electrical power distribution. Because you are now firing three high-performance solenoids simultaneously, protect your circuit pathways by routing your trigger lines through an isolated 40-amp fully sealed automotive relay like our Kleinn Part #340 to completely shield your cockpit activation buttons from electrical spikes.

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.
