So I installed the diy4x flip and switch on my blazer and installed 56" springs. Well the issue is as soon as I pushed down on the rear bumper the shackles fliped up. I do have the right hanger on the left side and vise versa. I have the long side of the springs pointed rearward and have 4.5" shackles on there. I did weld new perchase on my 14b and moved the springs forward 1.5" since the perch has 3 mounting holes. I ordered some 6" shackles to see if that will help but looks like I will have to move the hangers back a few inches. Strange cause the shackle angles actually look pretty good until it goes inverted from pushing down on the bumper.

. Keep it up!
