Kleinn Model 230 Beast Triple Train Horn, Black ABS

The Kleinn Model 230 Beast is a black ABS triple train horn for most full-size trucks and SUVs with onboard air. It's universal and the same horn used in Kleinn's HK7 kit and vehicle kits ending in -230, so it also works as a direct replacement.

In the box are three high-impact ABS wide-bell trumpets on a flat rack mount, a VX6003 (Vortex 6) heavy-duty brass 12V solenoid with its 51438 and 53814N fittings, and 12 ft of high-pressure 1/4" OD airline. On the rack, the assembly measures 18.5" x 18" x 7". Kleinn rates it at 155.1 dB at 150 PSI.

The flat rack is the main reason people choose the 230. Kleinn says it needs about 40% less clearance than its 500 series tri-mount horns, which opens up more mounting spots under the truck. If the rack still won't fit, the trumpets come off and mount individually.

Horn assembly only. You'll need an onboard air system and a tank of at least 2.5 gallons. Kleinn recommends its 6350 or 6450 systems. There's no model-specific install guide, but Kleinn does publish a disassembly guide for mounting the trumpets separately.

When you want more volume, the 6885 BlastMaster Plus adds a valve per trumpet and a 1/2" feed, and Kleinn rates it at 156.9 dB. Covered by a 1-year limited warranty.
