Welcome to the forum.
It depends on what you want to do to your truck but a popular modification is the Airlift 1000 or Coil Rite rear spring air bag kits. They stiffen the rear end and helps rear body roll. And if you tow, keeps your truck from sagging in the back. One for the best mods and not much cost, around $100 and easy to do yourself.
There are lots of good ideas and modifications on here and a large knowledge base. Have fun reading the threads and asking questions.
