Spring Swap height differences
Sorry I have to ask this. I have tried searching and reading the threads, but I can't find it.
I thought I had come across a chart here that showed you the different spring ratings and the expected height change difference from stock, for each engine option.
If you could point me to it, I would greatly appreciate it!

Thanks, I did see that post but I thought there was something more comprehensive than that floating around here. I remember it showing all the different spring options.
For example, my Ex has stock D and G and the chart included those springs. Stweart's post didn't include those unless I am reading it wrong.

I guess that I answered my own question, lol. I found a post my Mecdac on another thread.
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.

I am running the X code but with a Ranch Hand bumper. Probably pretty close overall to a stock bumper diesel with the W code. Felt overly stiff at first but after a couple days I got used to it.

I am leaning towards the W codes as well when I do the swap. May just go ahead with the V code everyone else is using, haven't decided for sure yet. Would love to put a buck stop bumper on someday, and thats why I am leaning towards the W codes.

Based on my experience, I'd go with the W's...I have Vs and I'm happy with them but I'd like a little more lift. See my signature for my spring upgrade.
