I've been contemplating lowering the 2003 Tahoe 2wd and have come across numerous ways to do so. A 2" front and 3" rear would be ideal. I've seen everything from torsion keys to spindles to lowering springs. Help! Can someone help an SUV suspension newbie? I've lowered many vehicles but most involved nothing more than springs, struts/shocks, and sway bars. Will someone please explain the difference with respect to the above? It looks like the McGaughy's 2"/3" could be a winner. (?) Or could I order rear Eibach's (2" or 3") and level out the factory rake? What else is needed? As usual price is important but cheap is not an option. Thanks for all of your help!
