I have OME rear leaf springs and extended shackles, I am getting old and can't remember the added length my shackles added. They are from eye to eye 5", I think it is 3/4" added lift does that sound right. My jeep sits about 4" of lift but since I put on 32" tires they are rubbing. My question is can I replace my old shackles with some that will add 1.5" to my lift without any problems.
