New guy here. Quick question on lowering (or actually raising) an 86 c10 SWB. The previous owner has installed lowering front spring hangers in the rear and extremely long rear shackles, bed cut and all. I want to get the truck up a couple inches to have some travel before the bump stops, currently about an inch. Am I going to screw up the geometry of the rear suspension by getting some shorter shackles taking into account the lowering front hangers? Or do I need factory front hangers first? I've got pics but I can't seem to figure out how to get them small enough. Thanks in advance guys

You can leave the front hangers and put the stock shackles in. See how it is and if you need more, add a leaf.

Keep in mind that your pinion angle is going to be affected as you rotate the rear-end about the pivot of the front spring hangers.
