the 4804 is a 3" drop coil for a regular f150, so its just a 2" drop coil for a HD truck

Front Coil Spring Set - 4804 by Belltech Suspension

if thats all thats changed on the front end, I'm guessing they may have cut a half coil off, or maybe even a full coil. But the coil alone would only drop your truck 2" in the front.

the pics are a bit small, but it does look like there's about an inch of fender gap up front, so my guess is they cut 1/2 coil and you're at around a 3" front drop. Rear looks like 4" which is probably belltech shackles & hangers on there.

To lift the front, a set of stock or 1" coils will raise it up an inch or two depending which you go with. The rear, see if you can get a pic of the rear shackles & hangers. If the hangers are riveted to the frame they're stock. If they're bolted to the frame they're drop hangers. For the shackles, if there's no extra holes at the top they're stock, if there's an extra set of holes then they're 2" shackles.
