Stock coil springs different heights?

[cdeal28078]

I noticed a while back that my truck sits lower on the right side by about an inch. The new 460 did'nt help!
I have swapped springs back and forth a couple times and even bought a new pair though I am now using an old set.
I read, I think here, about the springs having different heights from side to side to off-set the engine sitting farther to the right. Is this so?
I compared the 2 springs last time I messed with them and could not see a difference.
I plan on on doing the king pins some time pretty sood. Going with bronze. It would be a good time to figure this out while I have everything tore apart.
Any ideas?
When I put in the new springs a while back I actually cut a round off one spring to even it up. It worked but I cannot remember WHY I took those back out. I do know they are a little heavier varible rate spring so maybe it rode too hard. The 460 may make them more tolerable now though.

i think its the passenger side is suppose to be taller than the drivers side. if you cut down your new set your going to need a new one to replace the one you cut down to even the truck up.

Are they different enough to see by standing them beside each other? I only cut one spring from the new set and it made it set level which is why I am wondering. I know the engine sits towards the passenger side by about 2 3/4"

while this question is up, i have one that is related also. is there a difference in front springs on a 1/2 ton and a 3/4 ton? i would think so but my buddy said that they are the same. does n e one know? i have a set from a 3/4 ton truck and when i put my 429 in i will add the other springs if they will make a difference. sorry to butt in cdeal28078 but since i read this i would like to know also.

Yes, the difference between the left and right spring height (uninstalled) is obvious...about a 2" difference. When I was assembling my front end I noticed the difference and figured the longer spring would have to go on the driver's-side, to compensate for the added weight of a driver, steering box and column, brake hardware, etc.....but when it was put back together the truck had a very noticeable lean to the right. I switched the springs back around and the truck was setting level. Yes, the left side has a few extra pieces of hardware, but the combined weight of the engine/tranny being offset to the right side surpassed the little bit of weight from the left-side hardware.

When ordering these trucks you would specify the amount of weight you needed to haul/tow and would get the rear spring package to do so. However, the standard front spring rates would depend on the engine/tranny combo installed in the truck. F100 and F250 models with a 240/300 I6 got a 1055-lb front spring standard (a 1175-lb capacity spring was optional), whereas the standard spring for a V8-equipped F100/F250 models was the 1175-lb unit, with a 1250-lb option available. I'm pretty sure the difference was simply a slightly larger diameter of the spring coil....the overall size of the spring itself was the same, obviously.

Thanks Keith. I have never noticed a difference in the uninstalled spring heights and I have looked after I learned my truck was leaning. The ones in there now are stock ones out of another truck and they were identical in height. I wonder if after they are used for 30 or so years if they relax enough to be the same? The new ones I bought are variable rate and I am sure they are the same. Of course just because they are new does not mean they were produced by someone that knows that a ford has an off-set driveline.

When I do the king pins I will re-install the new ones with the one that has a round cut of on the driver's side.
Thanks for the clarification

I was going to say i know that wiuth all the torque the 460's and diesels put out they over power and seam to squash the pass spring.

I resently replaced my front springs on my 67 stepside. The truck originaly had a 240 and now has a 300. The front fenders were about an inch from the tires. The passenger side seemed lower than the drivers side. The new spring had the progressive rate (moog). After removing the front springs I put the old and new side by side. All four were exactly the same height there was no mention of a right or left from moog. After instaling them my truck looked like a 4wd. I took about a week of driving for the front to settle down and go back to 0 chamber. There is now several inches between the tire and fender It was definantly worth the swap.

Not to throw a wrench in but, I ordered a set of new springs for my 71 100 2wd and the taller spring came with a sticker/tag that says drivers side only. This seems to contradict what you guys are posting. Any ideas? Did they put the sticker on the wrong spring?

It's very likely that your new springs are wound differently from the original factory versions, especially if they're variable-rate springs. Therefore, I'd definitely follow their instructions and install it as they say. However, with factory springs, the longer spring definitely goes on the passenger side.

I got them from LMC. I'll follow their little sticker instructions but after reading the posts it will be with hesitation.

Will a 240/300 spring work under a 360? I am sending all of this stuff out for powdercoat this week and I want to be sure.

Thanks,

They'll fit just fine, but will just have a slightly decreased capacity (by 200 pounds)...which probably isn't enough to make a noticeable difference overall. It might make the front end sit a tiny bit lower, and would probably also make the front end ride a little softer. As long as you use some good-quality shock absorbers though, you'll be OK.

I planned on lowering it a few anyway so that might work out fine.....thanks.

Hello to all , i just installed a set of springs on the front also and i got them from lmc too but both are the same ! The truck dropped about 2" on level ground it is 15 1/2" from the ground to the bottom of the chase on both sides should i be concerned
