Had to replace my original one due to initial installation location. I have to say this new one is a solid quality part. Swapping it out was a breeze and my system works like brand new once again. Tech support went above and beyond in explaining the electrical end of the system. They saved me time and money and I greatly appreciate that. Thanks again!
I finally got it installed yesterday and horn is working again never a disappointment thanks alot
My horn is a single 24" trumpet like on an 18-wheeler. I'm running 150 psi tank pressure. I went through 2 of the cheap 1/4" horn valves in 2 years. They just quit working after 11 months each. I upgraded to the Widowmaker, and increased the size of the tubing from tank to valve. The difference is incredible! The horn blew OK as long as the old valves were working, but now, it's startlingly loud! It seems that even 1 horn benefits from unrestricted air flow.
Thanks again. Horns work again
The products are great and loud AF!
