I don't like the idea of RUF. What happens when you break a leaf pack?
I do love 63s, but not the huge shackle required to get any lift.
I may stay with OME up front and do 63's in the rear. About 2" of lift and 33x12.5s, 4.88, 4.7 case, and lockers! Very capable sleeper that'll get down.
If you break a spring the fix is easy. Just get a new pack. You'll need to add two extra leafs to a stock rear pack. It's a little extra work but you will have a better performing, riding and cheap set of springs than the trail marts. The likely hood of breaking a leafs is stupid low as long as you set your bump stops up correctly.
The 63's you should be able to run a 6 inch shackle and be ok. You might have to add a 1-2" block to level it out though. It should sit pretty level with ruf and 63's though, lots of Toyota's running that setup.
I can say for a fact you will not clear the 33 with the ome lift up front. The tire and the firewall try to occupy the same space. Which is the reason to go with the ruf which will stretch the front out a little and help that. Also keep in mind you'll more than likely have to do high steer.
