They don't advertise them as such but most if not all aftermarket shackles are lift of some sort. If you measure eye-to-eye and they aren't 4" then they're lift. Lift shackles don't not mean they have to be 1-1.5" lift. A 5" long shackle will give you .5" lift. Not really enough to make any significant difference. I think if they're under 5/8" they tend not to list them as 'lift'. Currie used to list the lift hight of their shackles though with all the anti-lift shackle bandwagon, they removed that. Notice they don't say that their shackles are stock height either.
As for adding shackles with aftermarket lifts, you'll want that .5" especially if you have military/double wrap on both ends of the leaf. Also, the ride will improve with longer shackles since any lift will add length to the overall eye-to-eye distance of the leaf. Most of the time the shackle is jutting out at more then a 45* angle which makes for a stiffer ride. Then throw in poly bushings and that stiffens up the suspension a bit more.
Hmmm... Interesting... I'll measure them tonight to be sure exactly what I have. I will say, though, that the ride is noticeably smoother, so regardless if they lift the Jeep or not, they are a big improvement (and not only on the ride itself; they also look much stronger than the stock ones!).
My shackles are currently pointing straight down, so I guess the length is good (whatever it may be).
Anyway, as you can see, these springs are not full military wrap at the shackle, but they were still a little stiff for my taste, but they do have poly bushings...
