Ultra BlastMaster Upgrade Kit 6890 for Model 730 Demon Train Horns

For Model 730 train horns. Increase air flow and push your train horn to unheard of decibel levels. The Ultra BlastMaster™ provides everything you need to add an additional two VX6003 solenoid valves to your Model 730 Demon™ train horns. The Ultra Blastmaster valve upgrade will push your Demon™ over the edge. Prepare your eardrums; they’re screwed.

NOTE: We upgraded the model 230 horns to the Vortex 6 all brass solenoid valve in 2017.  Model 230 horns with the all brass Vortex 6 valves use the 6885 Ultra Blastmaster kit. Model 230 horns still in the retail box will indicate if it includes the upgraded Vortex 6 valve on the full color retail box.
