I've got a 5.4L F-250 4x4. It's a solid front axle with leaf springs (I assume all of this year were like that, but for information's sake, there it is). Anyway, a 5.9 Cummins will soon go in, and I'd like some input on upgrading the springs. I know the 5.4 is 500ish lbs where as the 5.9 is more like 1k. So, if I'm looking for more weight capacity, what is the best way to go about this? I've seen the "add a leaf" kits, just wondering if anyone has had luck and if that actually ads weight capacity or just lift.. And I don't feel like putting a spring lift on it and then allowing the weight to settle it out would be the right way. Not sure though. Hell, for all I know, they are one in the same.. Let me know all of your thoughts. Thanks.

 

Ford x code front springs, part of the snow plow package

 

The X code will fit under the gas? That's one of the things I meant to ask, but forgot... will a set of diesel springs fit in the gas, or do they line up differently?

 

99 to 2004 are all the same, only capacity is different on the front springs

 

On the door what does the front weight have? 4400 5200 etc

 

Put the x springs on it as suggested.. Other code springs will not be enough imo.

 

 

99 to 04 all the same.

 

Thanks for the info all, going wit X Code.
