1st Gen 97 - 02 Expedition "Spring Codes"

[riderboy1961]

Does anyone know where I can find the Suspension "Spring codes" for the "Expeditions"?

I have a 1998 Expedition with spring code: SPR 15

I need the Chart that shows what the SPR 15 spring code means. What spring rating and such...

This Spring code I am talking about is on the Door Jam Vehicle Manufacturer Sticker. Located under the letters: SPR

Nobody knows what the "Expedition" spring codes represent for the spring ratings?

Update...
I called Ford from an online phone number, they cant find my answer.
I spoke to my local Ford Service Manager, he got back to me later that day and he could Not find the answer either.
It is Not a big deal. I was hoping to find out the Spring Rating on this rig (coil spring rating).

Can't find specs for the rear, all the lists I find don't have a 5. I would answer the question indirectly by extrapolation. E.g. measure your rear springs wire diameter, number of coils, and length. Then search all available options and create a matrix of comparable springs. Presumably the expedition springs would conform to other important spring characteristics such as elasticity etc. I did find specs for the Moog constant rate spring they offer for Expedition and Navigator. The uniqueness of the 5 designation probably has to do with the ends, as the upper and lower ends may be compatible with the air ride mountings, unique to these models vice the F150, for example. Let us know what you find. Here's an example of acdelco springs that could serve as a basis for a larger matrix specific to the expedition.
Part Number Code | Length | Rate | Wraps | Wire Diameter | Design Load
45H0290 | DE | 16.14" | 567 | 18 | 0.77" | 2218 lb
45H0291 | 2ACJ | 15.92" | 567 | 18 | 0.77" | 1941 lb
45H0292 | 3GH | 15.54 | 567 | 18 | 0.77" | 1722 lb

Get the idea? Jim

Note also the variable rate will differ significantly from the constant rate. So there's that as well.

Another thing, it looks like ford had many different springs but the aftermarket consolidated to around 3 options.

I helped a guy install Z71 springs on his Suburban. Pretty sure those same springs would work on an Expedition.

Does the Expedition(eddie bauer) have air ride? Then it has air springs. The coils are nothing special. There is 4x4 and 4x2 versions. You have 1 of the 3. Don't over think it.
