ok i think i got this narrowed down. common upgraded front springs are

CODE:
V - Part# F81A-5310-ADB
X - Part# F81A-5310-AFA

then the upgrades for the rear are:

CODE:
B - 3C34-5560-L (6840lbs, F350 SRW, and some F250's)
C - 3C34-5A975-D (F350 DRW 8250lb springs, rumor has it they will ride like an empty 40's model dump truck)

if those aren't the right part numbers i'll change them, but i got them off another ford forum that were listed for year models up to 04.

if this is the case, say the "X" codes give apx 2-2.5", do the "B" code rears give as much or is a block needed as well?

and if a dealer only wants $200 or so per spring pack, that's not to bad. so far i've only found Skyjacker that offers separate spring for front and rear (not in a kit). i found a 4" lift spring for front/rear for $565/pair. i really don't want to go up a full 4", 2-3", with tighter handling, would be good to go!

Great information.

 

I'm not sure how to start a new post but I'm wondering if anyone has had an issue with brakes pulling to the left and what may fix it? I know of mine and 4 others that do this. Mine has dana 60 and 70 front end and rear ends after market.

 

I think you need at least 25 posts before you can start a new thread.

 

Now that would be a silly rule if that were correct!

All a person has to do is click on the "New Thread" button and their very first post will be in the thread they create.

It's probably your slide pins sticking on the non pulling side.

 

Could the pins be sticking if they are brand new?

 

Yes if the holes aren't cleaned out and too much lube can cause a hydro lock on them. Maybe something on one of the rotors/pads also.
