Sorry if this is not in the right spot.
My son bought a 3" lift kit for his 1991 Jeep Cherokee Laredo, it came with 2 coils, 2 complete leaf springs and all 4 shocks.
Is this all that is needed? Will we need to extend brake lines? I've read some about sway bar extensions and longer Trac bars, are these necessary or can we lift it without those?
Trying to find out ahead of time so we don't get in the middle of it and have it stuck in my shop waiting for more part's. Thanks in advance

lefs/coils/shocks are all you need for 3"
Some XJ's like 99 and nwer do not like 3" lifts and more and require a spacer added to lower transfer case to avoid vibrations.

My 87 has been at 3" for 7 years I've owned it with stock control arms.
Recently i did change the front axle and the XJ it came from had a 3" with a trackbar relocation bracket, to recenter the axle after the lift.
also make sure you do an alignment after lifting it.
most instructions tell you to move the brake lines about an inch lower and explain how to do this at 3"
Even see Zome Offroad lift on stock control arms at 4.5" but would not recommend that far on them...
