Thanks John, Different question. One of my parts trucks have the 8 leaf rear springs. My driver only has 5. The 5 are pretty soft and spongy. I took the 8 leaf off and am considering putting them on my driver. The 8 leaf package appear to be like an overload with the bottom 3 leafs only functioning with a heavy load. Will these springs be way stiffer or only when loaded alot? I will only pull a small utility trailer about 5 times per year. It also appears the rear will be raised about 1 inch with the 8 leaf. Do you think this is worth doing? Mainly just concerned about being to stiff for the majority of the trucks use.
S716P Ford Van '81-'87 E150.
3.50 ratio.
9" ring gear
Non-limited slip
28 spline axles.
5A 18
5 = 5th year, 1985
A = January, first month. (B = Feb and so on)
18 = 18th day.
Jan 18th, 1985
BTW, if that is a usable part as it sits, $175 is a bargain. As to how you can tell, unfortunately, while you can check the ring and pinion for chunks, nicks, major wear and rust, you really aren't going to be able to check bearings or minor wear that could make it a howler unless you pull it apart or run it. Thus, is there any warranty from the scrappy for exchange within 30 days or anything at all? If not, try to pay less.

Jayson, I wouldn't swap the spring set. It will make your truck ride more like a buck board. I prefer the softer ride for my ol bones. I have the lighter springs under my truck, and load my trailers so that it is tongue heavy but not all the weight on the front.
When I load a truck on my 18ft trailer I stop pulling it forward when my bumper drops no more than 2". I passed a pickup towing a trailer/with pickup on board a couple weeks back, and it was pulled all the way to the front. The rear looked like it was sagging 10" and the driver was running about 45 mph. He looked as if he was fighting it.
Could the different leaf count on your two '64 F-100's be due to engine type and rated capacity (GVWR)?
I'm thinking your 223 is a little lighter than a Y-block or an FE.
"Six Cylinder Springs" are often rated lighter than "V8 springs", regardless of who the maker is.

Jowilker,
You and my father would've been great friends. He used to use that "ol' buckboard" comment all the time.
His solution for carrying 'max capacity" loads in his 1/2 ton was a pair of 500 lb. overloads, in the form of spring shocks.
A simple rear shock change was all that was needed and the truck always worked fine.
In fact, those spring shocks are still sitting in the basement of my parents house. Unfortunately, neither my father, or his truck, are around anymore to use them.
John, I am of your opinion and tactics. I think I might add 1 leaf out of a parts truck to "freshen up" the original ride. ( Not put in the 8 leaf pack) How many leafs do you have front and rear?
Elvis, your insight, as well, is appreciated. My parts trucks had larger motors in them. I would like to have met your dad.
That 8 leaf rear spring pack(appear original) was on 64 f100 f10cd540457 F10 = F100 2WD / C = 292 2V / D = Dallas TX Assembly Plant / 540457 = 1964, assembled May 1964.
I know the front leaf package was altered on this truck.
My daily driver is 64 f100 f10jd511744 F10 = F100 2WD / J = 223 I-6 / D = Dallas TX Assembly Plant / 511744 = 1964, assembled March 1964.
6 front leafs(appear original) // 5 rear leafs(appear original)
I have another 64 f100 ( looking for vin plate) // 7 front leafs(appear original) // 6 rear leafs(appear original)
All 3 trucks have a different number of leafs ( I know one of them has been altered but the other two certainly look original)
