Bought this April 2023 and installed it August 2024. Looks great on the outside, as a Hadley air horn should. Installed on our truck, pushed the steering wheel horn and pssssst…pssssst. No loud air horn sound, just air passing thru sound. Open the back panel and the throat diaphragm/orifice is broken. Looks like plastic?!? Now we have to buy another (going with another seller).

Great quality, deep sounding horn. Perfect for what I need. However, it is just the horn. No mounting hardware or air fitting. This is the part number for the air fitting - H11477S. Should be able to find it on amazon for around $20. You can also find the pedestals/mounts on amazon.

Be advised the air inlet threads are 7/16-24. Not a standard or common size in air fittings. The horns I removed from my Peterbilt 379 were also Hadley but they have the common 1/8”NPT inlet. I’m having a hard time finding the right fitting.Other than that they look and fit just like the Hadley horns I removed/replaced.

I’ve got three of these now.Good looking horns with great tone once you clean the excess adhesive out of the bells.But they’ve got the thinnest chrome that I’ve seen! They’ll pit in no time flat, and if you try to polish them you”ll be down to the copper underlay before you know it.I’ll powder coat mine and just give up on the chrome completely. Can’t properly rechrome them without taking the bells apart, and they’re glued together.
