I'd like to swap the 4400lb springs on my truck to 6000lb springs. This is for a 2018 F250 XL 6.2L Crew Cab Short Box 4WD. Can someone tell me if this is the correct part number?

F81A-5310-AHD

I've looked up the part and it seems like every site shows it being for much older trucks/SUVs. I just want to make sure before I order.

Thank you!

 

Okay I did a little more digging and it looks like they are the same dating all the way back to 2005? Also, is it possible the part number is 5C3Z-5310-CA?

if you know the right code this might help

 

Just saw your post. That looks right. What about the rear?

 

Thank you @digz! I'm fine with the rear as-is. I won't be towing anything serious, or hauling anything more than camping gear and a dog or two. A travel trailer is in my future, but not any time soon. The rear already feels light as it is.

I have a single axle 6x12 wood deck trailer that I use for hauling if it won't fit in the bed (I have a camper shell). Sometimes it has a motorcycle on it.

Mainly I'm just trying to increase the off-road capability of the truck. The front end is too low for my liking. Even with the diffuser removed, I'm still scraping the bumper occasionally. The 315 tires should help some, but I want the front end to feel lighter and not like it's going to bottom out.

 

Are you sure that higher rated springs will actually lift the front end? You might just end up with the same ride height and a harsh ride that you don't like.

I'd explore some other options for changing your ride height.

 

I would think the ride height would be the same. That spring fits both 250 and 350.
if you want to raise the front some throw a donut on the spring lol

 

It’ll ride like crap. Do a 1.5” level kit.

 

It's strange that there is such a dichotomy when it comes to this mod. Some people love it, some people hate it. Considering that I have 4400lb springs currently, and the truck feels like a boat to me, I think I'll be okay. Do bear in mind that I don't like the soft front end, and I want to have more capability off-road. Stiffer springs = more force required to bottom out the suspension.

Every snow plow package F250 I've seen is more or less level. From what I can surmise, the only difference is the springs. Therefore I would assume that adding the same springs to my truck would increase the ride height.

 

a while ago some one posted a sheet with the various springs. seems like all the springs were the same length before installation . the difference is the wire diam. which meens the higher capacity springs sqaush down less and give more ride height

 

My CCSB has the 5600lb springs which are the plow springs the gas trucks come with, the diesel trucks with the plow package come with heavier springs.

My truck has 2" of rake with the 5600lb springs. I've never measured one without the plow package because pretty much all the new ones sitting on lots around me are ordered with the plow prep.

My truck rides great with the 5600lb springs, it's not as soft as my wife's F150 but it's not harsh either. It's better than my old F250 but the extra wheelbase is probably a big part of that. I'm also running 60lbs of air in the front and 65 in the rear which is what the door sticker suggests.

My old truck had the "17 tires and were set for 75/80lns which is way too much for an unloaded truck and really made for a rough ride. I lowered the pressure down to what I have this truck set at but the tpms light was on all the time.

I'll go out in a bit and measure the height of the front of my truck to get you an idea of where mine sits with the plow springs and the 120lb ranch hand guard on it.

 

Thank you! I guess then the 5600lb springs are for gas, and 6000 are for diesel. Any chance your springs still have the little tags with the reference number? Or maybe your door code?

 

I have just the camper pkg and my springs are 5200. I have a gas f250 cclb 4x4 truck. My brother has a ccsb 4x4 gas f250 with snow plow pkg. His truck seems to sit higher than mine all around but it appears to be an optical illusion. As when you put them nose to nose the difference is negligible. Both are 2017 trucks same tire size and everything.

 

The front of my truck sits 41 1/2" high with the 5600 springs and a 120lb ranch hand grill guard on it.

Part number off the tag on the spring is
5C34-5310- ADD

The plow springs will get you a slight lift because they won't compress as much from the weight of the truck (back when the 250s sat pretty much level people would complain that the plow springs would make the truck sit slightly nose high) but the lift will be minimal.

If it was my truck I'd add the heavier springs and see what it looked like (it won't hurt anything and the heavier springs will offset the extra weight on the front) then if it still had too much rake then add the leveling kit.

ETA. i forgot to mention my tires are 275/70/18 which are roughly 33" tall. I see you have the stock 17" tires which will be a little shorter making your truck lower to the ground but the difference in rake is the number that matters. My rear is 43 1/2" so I have exactly 2" of rake. Compare that to what your truck with the stock front springs and see what the difference in rake is.
