Get a good trac bar? Or does that kit come with it?
Check out the CROK steering box reinforment - w/ 35s it's a good thing.
I always whack off just behind the lower front shock mounts on the axle, the LCAs hit here at full droop if not trimmed back.
When you remove your upper rear shock mount bolts, BE EASY! THEY WILL BREAK OFF! Use some heat and let PB Blaster soak them before.
Get a heavey duty TIE ROD, a big daddy one is only $80.
Or get the entire ZJ Grand Cherokee V8 steering from the junk yard and use this. It's way beefier than stock Cherokee.
Make some Tow hook frame mounts.
Get a gas tank skid plate.
