These horns have never been so loud. The 248 offers the power of the Viair 480C and incredible performance of the Shocker S4 to bring you the loudest compact horn kit on the market.
Simply put, this is the best 150 PSI compact train horn kit currently available. It's designed specifically for smaller vehicles where larger tanks may not fit. The compressor is extremely efficient and only pulls 19 amps at its peak. At 150 PSI, the Shocker horns are simply ridiculous!

Customer Video Review of These Horns
These are the exact same horns featured in this kit compared to other horns. The tests show the horns honked side by side at the same pressure.
