Replace your lower ball joints with OEM only, if you have not yet done that, read up on the lbj bolt thread too!
Read this thread.
If extended travel fronts you'll need limit straps so you don't over stress/bind the cv's.
What springs will you run with the rear shocks?
Upgrade rear links (or strongflex bushings at the min), panhard drop kit (eimkeith's pck), longer rear brake hose, parking brake bracket extender (you can diy this), extended bump stops (durobumps or perry parts). Longer sway bar links (3rd gen fronts on rear).
For the front, poly lower a arm bushings (whiteline, yes they are $ but they are steps above es). Longer swaybar links (rear 2nd gen 4runner on front).
