Not necessarily! For the front the number of leafs (2) are the same so no new u bolt needed there. The rear may not depending on which ones you need. But I bought the package deal which had all new hardware. It wasn't that much more than the springs (around $100 more for all 4 IIRC).


The lift mentioned is usually measured from the sagging worn springs. I installed new shocks (Rancho 9000) but they were the standard size and there is more than enough travel.

 

Don't want to take things off course here, but any idea what those numbers would be for either V's or X's on a 6.0 diesel?

 

Why, yes, yes I do.....
This is my Spring cheat sheet complied from various posts here on FTE mostly from old posts by bruce1954 and Monsta.

The following only applies to 4X4 EXs, the 2X4 rigs have coil springs up front. All EXs came from Ford with G code rear springs, the V-8 EXs all came with B (front B code is much different than rear B code, confused yet?) 4100lb, all V-10 EXs came with C code fronts at 4300lb and all PSD EXs had D codes at 4700lbs.
All the other codes discussed come from SuperDuty trucks (they came with springs that don't suck from Ford.)
Spring........Capacity.....Rate lbs/".....Max travel.....V-10 change.....PSD change
B (V-8)......4100lbs.......330 lb/".........5.02"...........-0.25".............-0.66"
C (V-10)....4300lbs.......350 lb/".........5.01".............0.00"............-0.37"
D (PSD).....4700lbs.......380 lb/".........5.14"...........+0.33".............0 .00"
S codes.....4000lbs.......370 lb/".........4.34"...........+1.22"............+0 .88"
T codes.....4400lbs.......390 lb/".........4.63"...........+1.42"............+1 .11"
U codes.....4800lbs.......410 lb/".........4.89"...........+1.60"............+1 .32"
V codes.....5200lbs.......430 lb/".........5.13"...........+1.77'............+1 .50"
W codes....5600lbs.......450 lb/".........5.34"...........+2.77'............+2 .52"
X codes.....6000lbs.......470 lb/".........5.54"...........+2.90"...........+2. 68"
W codes are from F-450s and X codes are from F-550s and other SD trucks with snow plow prep.

The above spring info has been gathered from posts here on FTE by "monsta" and "bruce1954".


So looking at the list Vs would give a PSD +1.5" and Xs would give +2.68".

 

And I'd make sure you have a rear sway bar- a couple of years did not come with them (mine included). Added one from an F350... best money spent yet!

 

Thanks much WE3ZS!! Racking my head here trying to figure out how much lift I'm looking at and what size tire I can do with the V/B swap and a 20x10 wheel.

 

If you throw a 2" shackle and do the B mod, 35's will fit. It's close, but mine work fine. Only rubbing is at full lock.

 

Well, maybe best money after new springs <g>. But it is a very good improvement especially on uneven rural rough roads. For flat highways and not towing - meh.


And while you are at it go ahead and replace the front sway bar linkages and bushing. They are very cheap to replace and most likely worn by now. The ones on my truck felt fine when you yanked on them but when I removed them trying to track down a knocking noise found that they were extremely worn.

 

Good info to know... Thanks! Do you remember what block you had to put in the rear after the B mod?

 

No change, stock Excursion block.

To clarify on my earlier post, 2" shackle PLUS V fronts, B-mod rear with stock block.
