Will the springs off the f350 fit on the shackles on my truck?

Yes but it won't make it level with the back

Woops. I meant the 4" lift springs for the 350. Will those match up or will i have to relocate shackels?

They should match up. I'm running F-superduty springs I. The front of mine and it sits about like a 4in lift.

Okay good. So ill need. Axle, sway bar, springs, u bolts anything else?

Don't need sway bars, I'm not running them. Axle, springs, trac bar and mount.

I meant trac bar sorry. What do you mean by mount? And any sterring parts? Also lug pattern is the same correct?

The mount from the track bar to the frame. Yes all pre 99 F250 and 350s have the same bolt pattern

Tie rods or anything along those lines?

nope, you can reuse the ones you currently have. just get it aligned after the swap
