I just recently purchased an e'99 F-250 that was bone stock. I've opened it up a bit with a turbo back 4" ss exhaust and the diy air filter. The next thing to take care of is the stance and eventually wider tires. I have a rattle coming from the front right that I haven't targeted yet and trying to decide what to do. The e'99 has a larger rear block (4" instead of 2") and I'm trying to decide if it'd be better to lift the front to level it out a bit or replace the rear block with a 2" to drop it. I use the truck for general towing and working out of the bed so it needs to retain a good bed height. I'd like to eventually run a wider tire but there is good tread on these tires that I need to burn off first. Would love some input.
