New control arms *required* to run 4.5" lift?

I'm wanting to piece together a 4.5" lift and was wondering what the minimum components would be to make this happen. Are new control arms *required*?

thx-

not required, but it should be on the list of things to get, and if you wheel at all your going to kill those lcas in a hurry. I'd at least get lowers, and look into an adjustable track bar. If your getting a track bar, get a quality hd one so you will only have to buy it once.

The Uppers are fine, the lowers you'll be short by about 3/4" which is liveable, but replace 'em with something stronger than stock, sooner the better though.
