I got Rusty's 4.5" kit which includes trackbar, LCA, brakeline extensions and a few other goodies. So far i've had no problems with it. Most people here seem to hate rustys', but I had mine shipped in just over a week with no problems, easy install (even though i had no prior suspension knowledge whatsoever) and everything rides smoothly. I fit 33" Baja Claws without any problems. Some poly spacers or ACOS up front will help because there is minor rubbing on the control arm, but not too bad. If you have problems and call, you get to talk to Rusty directly to work out the problem.
