so i bobed my bed then did new TG 5 " rears an the shackle comes up around the frame, then when i unflex it stays in the up position till i pry it down, i have stock shackles, but i did move the frount mount forward 6" and the rear back 2" like they say to do, so do i need longer shackles or did they just think a frame would be there to stop the springs from going up that far? what do your rigs do? i was thinking of building a bumper to be my shackle stopper, heres a pic

 

either move your rear shackle hanger back more, or get longer shackles.

 

x2.. What is your shackle hanger mounted to?

 

Looks like classic shackle inversion. If the hanger is back as far as it can go, likely a longer shackle is needed:

you could make yourself a bigger shackle or buy the 5in shackles that everyone sells. If you like the way it sits now then 5in shackles would look fine those springs are still going to settle a bunch.

 

frame. i guess i need a little longer shackles then because i dont want to move the springs back any more, they are the stock shackles

 

can't open up the instructions on T-G's website for some reason, but I think I went 6" up front and 3" for the rear mount on my 5" springs

 

well im guessing by your sig you have a runner and they say back 2" for pickups and 3" for runners, im just gonna do longer shackles and se what happens
