The reason I have been asking these questions is because I did a SAS and the front wound up being about 8.5" of lift. It was a little more than I wanted. I did a shackle reversal using the info of 2 Big Broncos white pages. I gained about 4 to 4.5" of lift. It looks stange with the back this low. I was thinking of using add a leafs. Is the the way I should go? Or, can I have new spring packs made and use the shackle reversal? If anyone has can help it would be greatly appreciated.
