Ladder bars are for the most part unadjustable. I believe the adjustors are just to set pinion angle. There is not alot you can do to get the front end in the air if it will not do it now. On ladder bars the instant center is where the front of the bars attatches. If you have multiple holes in this mounting point you may have a little bit of adjustment. If that is the case, the lowest hole should give you the most lift.
