im runnin 9000's on the rear of my truck and its awesome!!! They come up and go down faster than when i was runnin a pair of 3/8 ported 2500 firestones. And the ride is 1000 times better. Im also runin 3/8 smc's with 1/2 line and if id crank the pressure up a bit more, the whole damn truck would hop if i wanted it too!! Both highly recommended
I have used 9000 bag's since they came out and have only found one weakness....they pull on the clamp ring's and the cap pop's off..mostly this doesnt happen but some people dont have the restrant to handle it.u see it only take's around fifty pound's to raise a sleeve bag and any self respecting airride is at least 190 so you see the conflict..also the difference between up and down is only a few pound's making them very responsive that is why they make them with small port's..
Have 9000's on my 88 Toy,rides & handles grate!
I also think the asco is a much better valve. We use them On alot of our customers rides and never have a problem.
asco's are bad ass valve's.Iwas using them year's ago..before that they were used in hotdog factory's
