how to ID X-code springs?

I just got my build sheet from Ford, and it does not mention any Plow package, or heavy duty front springs. The only reason I thought it had them was the PO told me it had X-codes up front, and he used it as a plow truck.

Is there an easy way to visibly ID X springs?

--------------------------------------------------------------------------------

1998-current

Example: Y F 1 H - 1 8 C 6 1 2 - A A 2000 Taurus Electronic Climate Control Module.



First Digit - Year
W - 1999
Y - 2000
1 to 9 - 2001-2009
A - 2010 etc.
R - 2024
Second & Third Digit - Model
S1 - Aspire
S2 - Contour
S4 - Escort
S6 - Fiesta
S7 - Mondeo
S8 - Probe
S9 - Mystique
F1 - Taurus
F2 - Windstar
F3 - Continental
F4 - Sable
F5 - Villager
F6 - T-Bird
L1 - Bronco
L2 - Explorer
L3 - F150 - F250
L4 - Maverick
L5 - Ranger
L6 - Aerostar
L7 - Navigator
R1 - Aston Martin
R2 - Falcon
R3 - Mustang
R4 - Scorpio
R5 - Fairlane
R6 - LTD
R8 - S Type Jaguar
R9 - Mark VIII
W1 - Town Car
W2 - Cougar
W3 - Grand Marquis
W4 - Lincoln LS
W6 - RWD T-Bird
W7 - Crown Vic
C1 - Transit
C2 - Econoline
C3 - F250 +
C4 - Heavy Truck
Forth Digit - Design Responsibility (Mostly the same as before)
example: C - Chassis Operations
H - Climate Control Operations
T - Electronics Systems Engineering

Center Numbers - Specific component (Same)

Minor correction. Parts are numbered with even numbers except when in pairs - then even numbered parts are passenger side components and odd numbered parts are drivers side components.
Final two digits - Design Level.

AA first design, then AB, AC, AD, etc. BA or CA would be a part that was the same function as the AA but slightly different.

how does ^^^ that apply to this: X — 2C34-5310-AFA, 6,000 lb.

Where on the springs would the part number be stamped?

Sometimes information is spotty, but here is what I found out. I needed a replacement set of springs for a 99 4x4 superduty. I eventually found a pair of new take offs which then sat unused for many years being advertised locally on craigslist, and when I called , they were only 3 miles away. Since I never saw the truck they were from, I bought them based on the correct dimensions being checked with a tape measure , along with the seller stating they were for a leaf spring superduty. Stamped on the springs on the bottom towards the rear was 2C34-5310-ADB , so after many exhaustive net searches. I found reference they are "V" code springs from a superduty truck not older than 02.

They are going on a standard cab 7.3 99 F250 4x4 pickup when ever the weather gets warmer up this way, and considering the originals are worn out 200,000 mile originals , I hope it works well.

Start by getting the part number off your springs first, then see if what the chart listing I gave matches anything, and if not, search by part number you have found.

2C3= 2= 2002 C3= F250+ 4=design responsibility 5310= leaf springs ADB=weight rating of 5200 lbs.

Actually the year indicates the first year this part was used in production.

If it does have them, then he must have added them since they are not mentioned on the factory build sheet. I would think the door tag would match the build sheet, no?

Click the image to open in full size.

so this is the numbers off my springs. I noticed there are 3 leaves though, is that normal?

I see a lot of F81A numbers, but nothing ending with AED?

Is there any way to tell which F81A spring I have, and are they supposed to have 3 leaves or two?

I dunno, I guess I don't understand how to decode these numbers...

My springs are stamped F81AAED and RPN 2438, so do I go by the F81, or the RPN?

If F81, which one is it sonce there are several F81 springs listed above, but none listed as AAED.

If R springs, what does the other two letters mean in RPN, and what does 2438 designate?

also, my springs have 3 leaves, so I'm guessing the PO added a leaf?
