That is an interesting question. From what I understand the Accuair 3/8" valve reacts very quickly for what it is, and that is coming from Brandon Carter who just finished his dually and has their complete 3/8" system. Had I known now what I have experienced so far I probably would have just purchased the 3/8" Accuair valve and moved on, but I thought having a 1/2 valve would be better.
Let me explain... The issue here lies with how fast their ECU can read the data from the sensors. It simply cannot deal with the speed of a 1/2" system feeding the bags we use. So I had to use a ball valve on the exhaust manifold of the valve, and have played around with the speed of drop to get the system to read properly.
I am sure that a 3/8" system is fine for most folks, but for the duallies we build I feel that you need a greater air volume in order to raise these heavier vehicles quicker. I don't like the idea of waiting on a slow system to catch up when I have a pot hole coming up in the road, or a speed bump, or whatever the road throws at us. A 1/2" system in my opinion is better able to handle the quick responses that I feel we require for a fully functional air ride system. This is a belly button opinion and I am sure other will disagree, again this is only my opinion.
I know I have a hybrid system, and maybe I will need to change some components to better suit the whole system. The Accuair system right now is I feel the best unit on the market. Plus the whole iLevel system integration is excellent and works fantastic. I just wish I did not have to go to another supplier for my valve because making everything work seamlessly just takes more time and effort. We shall see in the end if it was worth it or not...
My recommendation for someone who just wants plug and play, go buy the entire Accuair system because you are going to be super happy with the product, the support after the sale, and the overall package.
