1. Ball joints get eaten alive on brodozers like that. And I can actually see the GIANT spacer on the front end and the stock control arms instead of proper aftermarket uniball style. This truck is not safe in this config.
2. If it's got a huge spacer on the front, it's surely got leaf blocks in the rear. Leaf blocks make me contemplate suicide.
A properly-lifted IFS truck shouldn't exceed 3" or so. You can use front diff drop brackets and whatnot for 6"+ lifts, but it's an exercise in futility. Add a leafs/extended shackles/custom leafs are the way to do the rear properly, and the front should have new coilovers and UCAs. You've been warned.
