What years fit our rigs, and are there any differences between the years and the f250 and 350's?

I am looking at getting a 2006 f250 rear stock leaf springs. Is there anything I should know or look for?

 

Here is some spring info that I copied and pasted. Hope this may answer some of your questions. I believe the '06 would be the same. If you can, check the codes.

There is a two-character spring code on the vehicle certification sticker on the lower doorpost behind the driver's door. The first character is the front spring code, and the second character is the rear spring code. A common spring code for a CrewCab 4x4 would be VB. The V means 5,200 pounds front springs, and the B usually means the rear springs on an F-350 SRW. However, some F-250s also have code B rear springs.

Any pickup can have any available front spring code - depending on options, and it doesn't matter whether F-250, F-350 SRW or F-350 DRW. Here are the spring codes for the front leaf springs on '99 thru '04 PSD 4x4 pickups:

T = 4,400 pounds @ground
U = 4,800
V = 5,200
W = 5,600 (rare on a pickup)
X = 6,000 (only with snow-plow pkg on a pickup)

Rear spring codes:
A = F-250 & Excursion (6,084 pounds @ground)
B = F-350 SRW (6,830 pounds @ground)
C = F-350 DRW (8,250 pounds @ground)

If you already have code B rear springs, then you already have the same rear springs that are on F-350 SRWs.

If you have Code U or V front springs, then you might like the code X front springs. In addition to giving you a little more weight capacity on the front end, they will give you a one to two inch lift of the front end.

If you wanted to really beef up the springs on your F-250, then put the code X front springs and the code C rear springs on it (they should bolt on). But be warmed it will then ride "like a truck"

 

Thanks for the reply. I am assuming that the 2006 f250 that I am looking at getting the rear leafs on do not have a 2 code spring rate example: vb. Because they dont have a spring in the front. Would there only be one letter designating the rear spring rating?

 

I would think that the 2006 should still have a code for the front springs. Even though they are coils instead of leaves, it would seem the spring rates to be different between an F250, F250 w/ snow plow option, or an F350. Therefore, they would have different codes for each. Here is a link that may help also. https://www.ford-trucks.com/forums/4...lder_____.html Scroll down through the thread and you will see the rear spring pack dimensions and part numbers.

 

Is there anyway to get this information for a 2006 F250? I'm pretty sure that my rear leaf spring code is A and I would like B or C's but I don't know If that information is correct for an 06, Thanks
