I was thinking about doing a home made shackle flip to get rid of my 4 inch blocks. I was reading the write up from the front page here but I did not see what kind of net lift the guy got. I currenty have 4 inch BDS w/ springs in the front and blocks in the rear. I found some one that with cut my stock rear shackles so that I can do this, but what I would like to know is what net lift I will have in the rear. Thanks!
