Hey Michael! The Pacbrake Alpha XD Pro Air Bag Suspension Kit w/ Internal Jounces # PB54TV includes two Schrader valves. A line will run from each air bag to its own valve so you can control them independently. This allows for the most customizable setup since you can level side to side.

What are you towing/hauling with your Sierra?

Have goose neck rv. Weight in middle. Would rather have one valve . Equal pressure.

@MichaelH you can always throw a union tee in there and tie them together if that is what you prefer.

@RobinH Was about to order . Just looked over instructions and it will fit if you have oem fifth wheel package. Why would you need it if not set up to pull? Which one do you have for 26 gmc 3500 duelly with factory prep ?

@Mike that isn't in our notes for it but I see it in the instructions now. Seems pretty worthless to me. I would honestly just get the Firestone # F2709 instead. They're more reliable anyway and you're going to save yourself some money.
