Front spring ratings?
19 F350 4x4 bought with a “camper package” . I’m wondering if there’s any way to decode the front springs?
Does this truck have 5200,5600, 6000lb rating? The part # is 5C34-5310-AEE. I’ve checked Ford parts, can’t find the “AEE”

AE coils are 5,200lb. You must have a gasser, as a diesel with Camper package woukd have ADs (5,600s).

Sorry.... yes truck is gasser SRW. I’d read where the spring rate with camper package would be “one higher” than computer selected as result of options chosen” , or wording similar to that.
The GAWR Front says 5200 on sticker. Im learning from you guys, guess that means the spring rates?
I’m assuming that the standard spring for F350 must be #4800?

And yes, the standard front coil spring rating for a 4x4 SRW gasser is 4,800 lbs.

This might be a fine point, but spring rate is given in force/distance, such as lbs/in. How much force is required to compress a spring a certain distance. The numbers described here are GAWR, or the weight the axle is rated to carry. There is usually a relationship between spring rate and axle rating, but that doesn’t have to be the case.

I recall Dana/Spicer rates the front Dana 60 in 2005+ Super Duty’s at 6,500 lbs max capacity (FAWR), and Ford offers it with a max capacity coil spring of 6,000 lbs.

^^^^ For the '18MY they changed the 6,000 to #5,090 I did not read anything that tried to explain the difference. I found my self wondering why even bother with a 10lb difference in the paper work. In the real world, in this context, 1/10 of a percent does not matter.
