xj coils vs. tj coils

[MADDMUDDER]

are these coils the same height? or are xj coils longer?
or just thicker. my recent fab bumper and stinger are causing my front to sag down abit. wondering how to level it off. spacer puck vs. coil upgrade?

ZJ coils are longer and stiffer, if you compare I6 wrangler coils to V8 grand cherokee coils, I installed them in my TJ.

XJ coils are the same as TJ coils

I talked to the RE rep one time about this, above info is correct, ZJ coils will give ~1" lift on an XJ, they're designed to support the heavier V8 up front.

For example when you look at the parts list for the RE 5.5" XJ lift kit, it lists 4.5" ZJ coils.
