I had an add-a-leaf up front (1.5"~2") and I didn't have any issues with the track bar where it was. So whether or not a leveling kit has a track bar adjustment most likely depends on how tall it is. Also, on 2005 and up, a track bar adjustment could be needed to properly position the axle under the truck again.
35s on a 3" leveling kit will work if and ONLY if you use a 8" wide wheel or narrower. I have 10s on my 35s and with 5" of lift I can make contact with the body. IMO, keep the wheel as close to the tread width as possible for best wear. Therfore, I roll a 10" wheel on my 315s.
As previously mentioned, it's the tire outside diameter that matters, NOT the wheel. How tall is a 33 on a 20 inch wheel? How tall is it on a 16 inch wheel? Yeah, it's still a 33.
If this is an '05 and up, a simple coil spacer alone up front will cause more problems than it will solve. The spacer shoves the axle straight down, as it does, the axle rotates forward creating negative caster, no bueno, batman.
The hard fact is, this isn't a cheap bastards game, do it right, or don't do it at all. Speaking of which, I took it in the shorts for 2 mpg when I went from 33s to 35s. If your budget is that tight, time at the gas pump should be considered.
Oh yeah! It's the center cap that gets in the way of the manual hubs, not the wheel. Although there are center caps with holes for the hubs, I don't have center caps on my truck.
