How much will i gain ?

[roofingbloke]

Hi All. I have a static drop at the moment, but just like most of you guys i want to get the truck lower, However i have 4" between lower a arm and top spring mount, Question is, how much lower will an air bag get me when the bag is deflated,

I dont want to drive any lower than the ride height that i have at the moment but want the truck to sit lower when parked up.

Could someone post a picture of a deflated airbag and measure the distance for me.

Thanks
