Great quality

I added these to my conductor special 844 nightmare edition train horn and there extremely loud!


Awesome addition

If you have the shocker 4 horn you definitely need to get the extra 2 bells. Totally worth the money



Would definitely recommend the upgrade to everyone! Worth every sweat and penny.


This adds the tone I was looking for

The shocker kits are LOUD. But with the addition of 2 additional horns not only do the make the neighbors relatives wish they had chosen dental implants as opposed to just crowns, they add the extra midrange tone that I believe makes trains jealous. My HOA hates them, the kid that reached into my truck and tried to unlock the doors will likely require counseling and so far they seem to be able to ward off Covid-19. I highly reccomend this upgrade for all Shocker kits. And all I needed to do to add them to the spare tire delete bracket was buy 18" of aluminum 1x1/8" flat and drill a couple holes and they fit right in with the other 4 horns.

Truly worth it!

WOW!!! This upgrade was definitely worth the purchase. Took max of one hour to install the kit. Now it vibrates my truck floor boards. It scared everyone at applebees when my stepson hit the switch.
