So while calling around today, I found a local recycler that has a 2004 F250 diesel with 52000 miles that has a suspension code on the sticker of V/P.

He's selling all 4 springs for 450.

I was contemplating a V code + 3.5" block, V + B code or V + modified B code.

Does anyone have any info on P codes for the rear?

My situation is a 2000 V10 Excursion...fronts are wasted, and with my day to day gear in the back, right now it sits just a bit down in the rear. I also have to tow a 16' enclosed trailer...I'd estimate the tongue weight to be between 760 and 860lbs, but I use a multi-ball hitch that puts the ball out a good 9" from the normal placement. As it sits now, I get about in inch to an inch and a half of sag when towing.

I'm hoping to get level when towing (with my day to day gear in my truck and existing trailer), and to not raise the truck too much (still gotta get inside parking garages). I would consider an inch of 'rake' acceptable with my day-to-day gear, but I don't want to go over that.

He'd sell me the fronts for 250 if the P's will make the rear too high.

Thoughts? Mileage on the springs acceptable? Height of the P codes vs. B codes vs. 3.5" blocks?

 

No-one has any knowledge of spring height for P codes?

I found some used F350 springs with these codes above. Not sure that helps, but the codes most guys here know are the ones for new springs from FORD. Seems those codes are different than what's stamped on the factory spring.

 

He said they were off of a F250, and I think he said it had the same number of leaves as the stock Excursion...I'm more wondering of how much distance I'll have between the center of the leaf bushings and the bottom when under load...I'm worried I may get too much rake.

Then again, they are coming off of a diesel 4X4 250. The diesel motor is heavier than my V10, but I added a little with the front tow hitch.

I'm hoping that the P codes would work in the rear since I carry maybe 200lb of 'daily' load in the back all the time (the storage box I made, tools, SAR gear, subwoofers, etc.).

I'd hate to get these, find out I have like 3" of rake, then not be able to get rid of them.

If someone had 'new' B codes and could tell me the distance from the center of the bushings to the bottom, I'd at least have a reference.

 

Found this with a quick search:

If that 8,800lb rating is correct, then according to this info I have saved:
The P's are rated higher than the C's are.

Hope that helps.

I sent the OP an email asking if he had ever installed the P codes on his 04 X.

 

holy cow, those r some serious springs.

 

That's combined rating. Each one would be 4,400lb, but yeah, some serious springs for sure.

Soooo...it's probably going to feel like the axle is welded to the frame unless I'm towing so e serious weight, huh?

 

Before I go any further down the road (literally, down the road to the recycle yard that has them)...2004 springs should work on a 2000, right? No changes to the frame or mounts?
