### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Better than buying the entire horn which is 50 to ...
  

*by D***S on Reviewed in the United States on January 16, 2015*

This was very simple to replace in the KC 500. Remove speaker grill, remove horn, take apart horn (4 metric screws) and lift old diaphragm out. Replace in reverse order. It works perfectly. Better than buying the entire horn which is 50 to 60 bucks. The weird thing is that just by looking at the old diaphragm I couldn't see why it failed. But it did. Heck my eyes aren't as good as they used to be anyways.... It was delivered on time as promised and saved me allot of money. Amazon Prime is wonderful! It has already paid for itself this new year. I think it is also a wonderful thing for all the freight guys like UPS, FedEx, and the like.

Perfect fit. Works great.

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Good product, good price, but not a drop-in replacement
  

*by T***S on Reviewed in the United States on June 29, 2016*

As another reviewer stated, you will have to do some minor surgery on the horn to get it to fit. The connectors on the OEM diaphragm are located on opposite sides, and the ground connector is smaller so it has to be replaced or soldered. It's no big deal if you'used to this type of work. It works well and is cost effective. 4/5 stars simply because it's not a drop-in replacement
