thats what idid to mine,,a2 front springs,,3 inch blocks in the back,,i did 3 inch longer shackles,,didnt do anything though,,,,oh get a little more lift,,,carefully cut the lower spring perch off,and reweld it up an inch or 2,,i think you can only go about an inch,,,,,,,,watch the right side driveshaft,,it canrub the top of the front control arm mount,especially when on it hard in a right hand corner,,idid make a front suspension limiter,under the control arms,so theywouldnt rise or top out too much,,have a blast!!
