If you have a body lift, you must have a TJ. Having said that, if you are going for 8" of lift, This would be my suggestion:
Remove the 1" pucks, and install a 2" or 3" body lift.
Install a good 4" suspension lift.
Add 2" spring spacers on top of that. (the alternative to this setup would be an ultra-pricey long arm 6" system)
You will of course have to add a slip-yoke eliminator to the t-case, as well as a new rear drive shaft. Something will have to be done about the severe angle of the steering components. Maybe a high-steer conversion, along with a dropped pitman arm (which should have come with the 4" kit).
And don't forget regearing axles for the larger tires. The rear Dana 35 will not survive, and will have to swapped out.
As you are probably figuring out, this is a expensive and labor-intensive operation you are looking at. Costs for this type of mod go up exponentially at these lift heights.
Why so high? What size tires are you planning to run?
Your finished product is going to be a fairly unfriendly beast to drive on the street, as you probably know.
Not trying to discourage you, just being honest.
