Wondering you makes the best shackles and which one gives you the most lift. Looking at AC and Calmini.

Who makes the best is more a matter of opinion. I can say both of those mentioned are advertised to give 1.5" lift... i have heard of some people getting 2" out of the AC's but it probably just depends on leaf pack wear/sag.
I have the AC's; chose them because they are beefier with the crossbrace... for the extra 5-10 bucks I would go with AC. No powdercoat to worry about flaking either; just rattlecan them if they get scratched up.

Daystar and SLR have shackles available as well. Daystar are 1.5" lift and SLR are .75" lift.

AC shackles are nice solid pieces. Gave me 2" when I first put them on
though I believe the rear has sagged a bit since then.
