Did a search and didnt find much. Would a 2 1/2 inch shackle flip, with a 6 inch shackle give me 4 inches of lift with 56 inch rear springs (I think thats what my 91 k5 has)? Would it move my axle any? Anyone running this set up? Thanks.
 
The shackles will lift the vehicle half the difference in the extra length. So if the shackle is 1" longer than stock it will lift the vehicle 1/2". Blazers are all 52" springs in the rear from the factory. You would need a shackle that is 3" longer than stock with a 2 1/2" shackle flip to get you 4" of lift. I would highly advice against going that much length on a shackle. Why not just buy a 4" shackle flip and sell the 2 1/2" ?
 
I dont have a shackle flip yet but im going to be getting one. Dont longer shackles help with articulation?
 
Trust me , stock shackles , and a 4 inch flip , you will hit the inner bedsides with your top inner tire edge easy .
 
also w/ only a 2.5 shackle flip and a 7inch would be a horrible shackle angle(ride and flex will suffer) with ur stock 52inch springs. but a 4inch shackle flip and swaping the sides w/ a 6inch shackle flip is starting to be the normal for 56inch springs.

There's more to it than simply a longer shackle. You have to have the proper shackle angle for a longer shackle to give you more droop. For example, if the shackle is straight up and down a longer shackle will only give you a little more lift, but not make any difference in the articulation.
