Air ride height adjustment

[Humation]

Anyone know a sure fire way of making sure the rear adjustment is level - outside of tooling with it and rechecking multiple times? I have a 6" FT lift and it seems to be lower (body)on one side. Measure from top of tire to the body - or from street to top of rear bumper? Other ways?

Thanks

Does anyone make a replacement bar that has an adjustment to raise and lower the air susp?

You can measure from bump stop to diff tube to eliminate uneven road surface when checking adjustment
