What Is the difference in a 2wd coil spring and a 4wd coil spring and is there any reason why i couldn't put 4wd coils on my 2wd

 

Bump and add.

Don't want to hijack but;

Are 1/2 3/4 & 1 ton front coils all the same on the 2wd trucks? I cannot find any specifics on them. I have a 460ci in my 74 s/c which obviously weighs more than the 6 cylinder some of these came with. seems odd to me.

Number dummy just in the last couple days posted the info for the 67 to 72 trucks and they were the same between f100 and f250 but there were 3 different spring rates for 6cyl and v8's. I'm sure that is the same for 73 to 79's

 

There are many different sets of springs for the 2WD pickups.
Is your s/c F100, 250, or 350? And what is the front axle capacity (warranty plate or it's also listed on the paper cert. sticker on the door jamb).
I can look up the p/n for you.

 

Are you asking if they will lift your truck? The simple answer is NO, they wont.

 

Actually no i'm not really worried about lifting it but its gettin about that time to get new springs and i saw some 4wd springs and they looked alot heavier duty than the 2wd

 

1974 F250 2wd s/c I don't have the truck with me today so I can check the front axle rating tonight but the total gvwr is 8100#

Thank you,

Here is the page from the Ford parts book. Your truck is third from the bottom.
There are three different pairs, depending on the capacity of your front axle.

 

wow,
Thank you very much!

I saw the reply posted by MikeoOoOoO showing the ford parts list for front coil springs, is there another ford parts list that I can look at please showing spring specs for a 1974 F250 single cab, 4 x 2, 300L straight six, Gross Vehicle Weight 7500lbs that I could look at ? Or is it the same one?
I am rebuilding a vehicle that I found standing on blocks in the bush for 20 years and the front camber setup looks like a VW Beetle without the engine so I need to talk to my local spring guy about new ones to replace these stretched ones.
We don't necessarily have some of the spring data readily available here in Africa, so I would need to specify my needs. Thanks kindly

 

Greetings Roland.

Be patient and one of the parts guys with the Master Parts Catalog microfiche will chime in soon.. likely ND, JEFFAFA, or Mike.

 

HIO Silver,
Thanks for your reply, I was awaiting a reply from the others before thanking you for your response, but so far nothing, must be away for Xmas . Mine is a RHD assembled in South Africa by Ford South Africa sometime 1974 or just after and the VIN plate layout on the door does not read like the US standard, although some of it is decipherable by checking the Vin plate vs Ford forum info , but it does not show front axle capacity only a Tare of 2005 kg (dry weight) , a Gross Vehicle Weight of 3400kgs so very little is is known about the build options except that it is a 1974 F250 Custom (base model) , no P/S, A/c, fan, heater,demister, just side feet vents and vent window for air. Ford's factory local factory records were not kept filed due to a partial pull out just after that time and today nothing can be found of that era.Much of the parts like rubbers indicate manufacture in Canada , I'm sure much was also sourced by Ford SA from the US at the time.
The VIN plate data mentions S&A, B&M; AX , Body Work 2J PE ( Port Elizabeth?), Serial number 37373, Sido Number , EIH Nr. 715654, Engine C,engine number 52449, Transmission N, R.Axle A, Paint ON, there is a sticker on the engine tappet cover which says May 1974, Series 300 engine and that's it.Occassionally on the front ally grill and other places I can find 1974 stampings. The underneath NP gearbox and Dana 60 diff number and ratio ID plates are clearly identifiable, also the engine number but absolutely no chassis number or axle load data stampings except for the data shown on the ally VIN plate.

Regards
Roland

 

2vs4x4 they differ in other more important way. The 2wd has pigtail on bottom and regular top. 4x4 has regular top and bottom. Look up one of my lifted 2wd postings. Shows what I used to level my Supercab 2wd with a 460. compare. Last is my sons 75 we are starting to work on and mine in the background. If I had to do it again, I would put the taller lower spacer rather than the stock one that came with the truck. I had them but did not want to press my luck, as I had to n\have the beams bent to get the camber back to stock. The front is 1" lower than the back, the spacer would fixed that.

 

Thank You Mofoco1 for sharing your expertise and your pics. You are blessed to have your son involved. The pics show what appears to be good stuff.
My front coils on the '74 F250 300L 2x4 appear to have two pigtails, one each end, strangely. Because I'm going for a lower and softer ride I cant cut a coil off to try and level the truck chassis. I have however taken the two lower support leaves off the rear blade stack, which had seven blades , dropped the rear by by one inch, still have more than 12 inches of travel left.. The front travel between the rubber stops and the I-beams is 2.5inches. I am looking for improved cross axle flex to get the smoother ride and to prevent lifting of one rear drive wheel ( no LSD) to maintain maximum traction when I go off to the boondocks fly fishing .I also have no torsion bars, so cant rely on them to push the other wheel down. I'd appreciate any suggestions you have.Being in my 70's I don't want a struggle to get out of the boondocks, but I am convinced that with the right setup and careful driving practice I don't need a 4x4 vehicle.
Kind regards
