I installed no lift shackle brackets and boomerang shackles with 3.5" RE leafs. I wound up with 4.5"+ of lift and kept about 200 lbs of extra wait to get them to settle. But they never looked like that. Unless you have the rear extremely overloaded, I agree with 4.3.

Yep. Looks that way to me!

I understand what 4.3 is saying. That pack was assembled with ALL curved leafs. They are pressed together then the center bolt is installed. because the bottom leaf is so long and curved, it actually presses up on the leafs on top and this is what causes that wonky shape. If you remove the bottom leaf and replace it with one the same length, but flat. It will take out the wonkyness. Here is a leaf pack from clayton off road and you can see how flat the bottom leaf is.

Be very careful when removing the center bolt. The springs are under tension. The easiest way would be jack up the jeep with Jack stands under the frame. Then using a floor jack to jack up the axle to where it just about lifts the jeep off the jack stands, pull the wheels, remove the U bolts and loosen the center pin. SLOWLY lower the floor jack and just when the center pin starts to get tight, loosen it the rest of the way. Now be careful cause the axle is just kinda floating on the jack. Then slowly let it the rest of the way down far enough to get the center pin out and the lower spring. Insert the S10 spring and reverse everything from there.
