If your lift is only 0.5" higher you might not need to do much. You could get the shackles, install them and then test each corner for "full stuff" and "full droop" to see if there are any issues with tire/tub clearance (will need the 33" tires), brake line length, and shock length. Then a test drive to check for driveline vibrations and steering issues. I suspect that with only 0.5" additional lift you may have problems clearing the 33"s. My mechanical/suspension experience is iffy at best :lol: so there are far better sources of info.
The RE 4.5" kit will include everything needed and you save the cost of the parts you might buy now and remove when you get what you really want.
