This will get you a 4 1/2" or so total added height to what you have now. You could easily fit 36" tires with this. This would be the cheapest and easiest you could probably do it in your driveway in a couple of days with a decent jack and a average tool kit. I would get longer length shocks instead of shock extenders. Definately get longer brake lines youo don't want to risk overextending your brake lines and causing a tear. I would do the lift first
measure your travel, wheel well opening and figure out the tire size that will best fill up the space while not rubbing. Be sure to actually measure the tires
you plan on getting some tires are not what they claim to be (kind of like 2x4's) I have seen 33" actually measure 31 3/4" and some were 32" brand new
not even with any wear so figure on bringing a tape measure to the store. Don't get cheated if the brand you like is actually 36" tall for a 38" maybe you can talk the tire shop into lowering the price of the tire since it doesn't match!!(that's false advertising!!lol Jk)
