I use TNT 1.5" shackles on my MJ. There is no need for a boomerang schakle on a MJ. I took mine off of my XJ. I did redrill my mounting hole in the frame mount to increase the shackle angle for a better ride and increased droop.
The TNT shackles are well built and HD. Here's a pic.

And no I'm not affilated with them I've been TNT on most Jeep boards since 2000.
Well, I'm not sure if I need the boomerangs, what constitutes a need? I was directed to them after a discussion on Jeepforum... and did you mean to give a link to FS Chevy drop shackles :???: Again, I want to make sure that these are for use with the stock springs (well, they're aal, but whatever)
