Need advice!

Hey Y'all!
New to the lifted world. Recently purchased a '99 F-350 for the daughter. Has about a 4" lift, make unknown but has Rancho shocks. Tie rod ends, drag link, and Pitman arm ends are shot, showing 169,000 something on the clock. What grade replacements should I look for. Pitman arm looks stock, does it need a drop for better angle, longer life? Girl says the ends are F-450, does it matter?

4" lift should have a droped Pitman and a drop track bar bracket.
Moog or XRS? seem to be what most use.

Ends of what are F450?

The actual tie rod ends say "F-450" on them. And I believe it has a dropped track bar.
