As title states. I had someone else install and I never got the instructions. I need them to determine which air spring system to go with or if I can make the one I have work.
There are 2 sets of holes on the hangers and 2 on the shackles. I am on the higher ones. I want to know exactly what the lower holes are designed for. Pinion angle level of drop etc etc etc.
I am really tired of bottoming out. I also can not tow my trailer with anything in it cause it rides on the axle. I would like to raise up an inch to be level to.
I found this thread

Looking at these

Bought these.

They don't fit too tall.
Sorry for the long post. I don't want to buy the wrong thing again
