Rear spring code help
Hey guys, I have a 1997 F250 and im swapping out the TTB for a Dana 60..I was told to use the Reverse shackle kit and Superduty V code front leafs..Got all that. Now im trying to find rear leafs. Been told to use B Code Superduty leafs. Found a set of leafs that have 2C34CA stamped in them...Any idea what code they are?

The spring codes are in the bottom right corner of door sticker under SPR.

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".
BTW, NEVER change leaf springs without replacing all the U bolts with brand new U bolts.

That's the way I interpret it. The exception is that some F250's have B code rear springs.
Hopefully Stewart_H will chime in.
Any markings on the springs? EDIT I just noticed the 2C34CA in your post. Don't know what that means.

that might help you identify the springs and the mention of 2C34CA.
Edit : It takes awhile for the page to fully load so be patient.

Are these weight ratings per leaf spring or total? Someone told me that they are total?
Who makes the OEM ford leaf springs?

I have "B" code rear springs on my F250. They have an ink stamp with YC35-5560-CA and metal stamp YC35-CA and RPN 2800. They are F350 SRW springs. They were not original to my truck (per Ford build sheet for my VIN), but were already on it when I bought it.
This link may help also. https://www.ford-trucks.com/forums/1...spring-id.html It does mention the number you have.

Any chance you know where to find these codes for a 2012 F-250 and F-350?

Dunno. You might wanna try the forums that cover that year truck.
There might be someone in the 2011/2012 diesel forum or the Super Duty forum that might know.
