My 1990 f150 xlt 4x4 extended cab long bed truck has a very jacked up rear end. The previous owner told me he put f350 leaf springs in the rear which I believe since I get minimal suspension sag when loading it up. The problem is no one messed with the front so it looks like a drag car going down the road. What springs should I get to lift the front, and is there more involved than just springs? I'm not shy of the work I've just never lifted a truck before so this is new grounds part wise. No leaf springs just a coil spring and a shock

 

You should put the correct springs on the back. Changing the ride height of the TIB/TTB suspension is NOT easy, cheap, or comfortable.

 

Just checked out what you meant about the TIB/TTB suspension and I knew my truck had a weird front end but I didnt realize it was this weird. I always knew camber wasnt adjustable but I didnt fully understand why. Thanks for the push in the right direction to understand what's going on and what to expect work wise. The kits I've been finding online didn't really show this until I looked up a lift kit with a TTB suspension. The front end is sitting lower than it should so Im going to play around with some springs until my camber is correct, right now its negative. I have replaced tie rods and ball joints. Thanks man for the info

 

The TIB/TTB suspension isn't intuitive, but it's really just a single-A-arm suspension (whereas most are double-A-arm). It gets confusing because they're overlapped, and not parallel or perpendicular to the vehicle axis. And yes: camber is adjustable via the cams on the upper BJs. They're built with solid camber cams, but adjustable cams are available.
