There are a thousand ways to run your proposed set up. Any shocks would technically work if you had the right length shock towers. (following?) just adjust the steering stops to avoid rubbing on the leaf springs and your tires will last a lot longer. Wheel spacers? Better off with different rims. You'll maybe need to extend your bump stops if you do some trail riding and flex a bit. With your track and swaybars on, I wouldn't worry about bumpstops, you'll never need them.

I agree with Anti. As for shock length and 'do you need longer bump stops', it's easy to figure after you get the lift on. Here is a link to an exact post I wrote a couple days ago for someone else.

I have a 3.5" Black Diamond, well 3" now but I got some extended bumpstops a few weeks ago but I'm waiting on my buddy to drop them off. I know I need some because my drag link is hitting the tie rod. That's what is limiting my stuff on the drivers side. Plus the springs are flattening and nearly inverting. I've wheeled like that for years but I'm starting to take care of the little things. Hopefully it will keep the steering from hitting itself.

As for shocks you'll just need to measure after the lift like Don and Anti mentioned.

I have a jeep...and it is modified...I win.
