When I air out my bags and at the very end the dumps make this god awful growl sound. I dunno how to explain it I wish I could record cuz it sounds terrible, its like the valves are friggin farting or something lmao. Anyways I'm curious what the hell is making it to that! I've had it ever since I bagged the truck but I guess it never really botherd me til now.

Wow I have never heard a problem like you got. Do u have the air mufflers or any type of reducer in the dump valve. I don't even know but I bet it sounds really funny since its got a farting sound to it.

i know the sound you are speakign of, the valve may not be opening fully, the sound you hear is the diaphram slapping open/close and vibrating inside the valve housing.

:stupid: Make sure your electrical connections are all good, and make sure that the valve is clean. Take it apart and inspect it.

Yay more responses...Anyways yea they still make the pssh pssh but its the last second it makes the growl sound. From dave's reply it looks like its not the muffler. I'll try cleaning em up and hope that works but what should I check for electrical exactly?

Yah, he sent me those also. I installed them, but it dumped way slower and didn't make the classic pssst, so I took em off. Check your electrical connections sure, but I don't see the valves being dirty, considering it's happened since the valves were new and that just the dump valves are doing this.
