while putting the bags in, check for places where it will rub, you will probably need to trim the spring pocket. there is a lip inside the spring pocket, kinda like a half pipe, you have to cut that off. When the bag is in, it will bulge out a little, towards the wheel, so you will have to eyebrow the spring pocket ,like a half moon shape, an inch at the most. The valve should have 3 ports on it. In 1 port the airline from your air tank will go in, The other port will go to the airbags and the third port is for the air to dump out of. Hope this helps.
