hey everyone, i just got a 2004 chevy silverado z71 and i want to lift it either 4 inch or 6 inch and cant decide, it depends on how much other stuff i would need to buy for the 6inch to make it right? any suggestions? and i am looking to buy 18 inch xd rockstar rims and run bfgoodrich all terrains size 285? would that look good? thans alot!!

There's a lot of good info on this forum about lifts and tire size. Do a search and see what you find. With a 4 inch lift and 18 inch rims a 285/70 will probably fit, a 285/75 may not. Depends on the offset and backspacing.
