HornBlasters Rocker Horn Only Kit - 2 Trumpets - Hardware Included

I have these horns along side my Viair Onboard Air system running a 110/140 pressure valve and the supplied 5/16" hose.The sample sound on Hornblasters website had me thinking these were more like a marine tone but these deliver a nice clear deep sound. These 2 plastic horns give my old triple metal horns a real run for their money. Very pleased.Pro tip: remove the solenoid mounting plate to find its flow indicator.
