Honestly, you probably won't believe me, but for the last two days, the search feature is not working for me. I try to search, and it just keeps me waiting. Not sure what the deal is.

Anyways, I'm trying to understand leveling coils. Are they a stiffer spring? Or are they just taller? Is the purpose of them to raise the front end a bit? Or to give a heavier duty spring up front? (I'm assuming by leveling they mean leveling the front height to the back).

I've been looking for an 05-07 F-250, and I need to put a plow on it. I know the normal springs for a SC V-8 and V-10 are 4400lbs. Snow plow prep springs were Ford 5200lb springs. The 4400 trucks seem to sit a bit low in the front compared to the back. The ones I've seen with the Ford 5200 springs on them seem to be more level in the front. Or am I just imagining that????

So, if I find a truck with the 4400 springs on it, could I put leveling springs on the front for the plow (do leveling coils level the height as well as provide a higher weight rating?). Or should I just stick with the Ford 5200lb springs? I like the look of the truck sitting level from front to back, so would the 5200 springs accomplish that as well as prepping for a plow?

Thanks!!

 

For a plow....6000lb coils. That's what's on my 07 F-350 PSD with the snow plow prep package.
Getting the snow plow on Friday. Going to be installing load assist bags in the coils as well.



Leveling coils are taller, spring rate and weight capacity vary by spring. Icon and Bilstein for example use progressive rate coils so the initial spring rate is actually softer than stock. Not what you want for a plow in the 700-1000lb range depending on what plow you go with.

 

Yup.. at least 6000lb coils. My truck came with 5200lb ones and they were far too soft. My truck is the lightest configuration you can get and it would bottom out... 6000lb coils cured that for me and the ride was actually better with the stiffer springs.

 

Wow, 5200 in the single cab still bottomed out??? Thanks for the info. I know DC has the diesel which calls for heavier springs than the gassers do, and that the 6000 were rated for his truck. I didn't think the 6000 would work well on the gassers.......I figured too stiff.

Guess I was wrong!! THANKS!!

 

I have an '06 PSD single cab with the stock springs and a leveling kit(Rubber spacer) and have never bottomed out. The problem I do have is that because the truck sits so high with the plow on the ground, the angle at which the plow meets the ground is to steep and if the ground isn't frozen it "rips" up everything.

 

For the plow, they'd be good.

Anyone know the weight of the V10?


I know my 07 PSD (Super Cab, Long Bed) unloaded weighs 4780lbs at the front axle.
My plow weighs 842lbs and another 75-105lbs for the bracket on the truck.
With my 6000lb Front Axle Rating I'm under it by 200-300lbs.....but still going to install load assist bags in the coils which are good for 1000lbs.


Depending on how much lighter the V-10 is, I could see it going over 5200lbs depending on what plow you get.



How big of a spacer are you running and what kind/brand of plow are you running?

 

I do not have the exact motor weights off hand, but you are looking at the V-10 being about 475 lbs. lighter on the front axle when compared to the 6.0L. The 5.4L would be about 625 lbs. lighter...

 

Thanks for the info.

Based on that....a big plow would put a V-10 right at or slightly over 5200lbs at the front axle.

A smaller plow like a 7'6" straight or 8' straight would be under....8'6" straight would probably be just under depending on the brand.

 

DC Special,
the spacer is 2.5" the plow is a Curtis snowpro with an 8' blade. I had the same plow on my '03 superduty with a v10, no lift and it was fine.

 

Damn, how did I know it would be a plow I've never seen before, lol.

I take it there isn't any vertical adjustment for the bracket on the truck?

I know some give you vertical adjustments at the truck and then you can rotate the blade on the plow frame as well.

 

I Have it as low as it will go.

 

It would be a 7'6". I'd be doing my own driveway and my parent's only. So I was going to just use the Boss 7'6" SuperDuty straight plow. That plow would be sturdy enough to handle what I'm doing for a long time. I know there are bigger plows out there, but I want to stay as light as I can while still being beefy enough. The lighter the plow, the less abuse on the front end. I'm tyring to get the best longevity I can out of a newer used truck and a new plow.

 

If you are going to replace the front coil springs go through ford. I know, its not every day that ford factory parts are cheaper then aftermarket. I relaced mine on my 06 supercab V10 4x4 due to heavy grill gaurd and wanted to up grade the springs in the front end. I got them through ford parts $54 each, if I remember there are 4 or 5 choices of coil springs.

 

I think that these are the correct part numbers for front coils:
6000lb front coil PN: 5C3Z-5310-CA
6500lb front coils PN: 5C34-5310-BA
7000lb front coils PN: 5C3Z-5310-AA (used on the 550, and need to be purchased at a full line Ford truck dealer)
amost all are under $50./ea

 

I got my coils from Ed, FTEParts guy, and the service was great.
