Yes. There was instructions at 4crawler.com when I bought mine. Basically you loosen all the bolts and removed all the nuts on one side then jack the body up slowly on that side and replace them all. Then repeat on the other side.
Spray some PB blaster or Penetrating Oil on all the nuts first and let it sit. Some of the bolts can be a pain to loosen if you got a lot of rust. Also remember to check your fan shroud after doing the lift for clearance.
