2 to 2.5 inches of lift depending on what your original spring code is.
from my archives
There is a two-character spring code on the vehicle certification sticker on the lower doorpost behind the driver's door. The first character is the front spring code, and the second character is the rear spring code. A common spring code for a CrewCab 4x4 would be VB. The V means 5,200 pounds front springs, and the B usually means the rear springs on an F-350 SRW. However, some F-250s also have code B rear springs.
Any pickup can have any available front spring code - depending on options, and it doesn't matter whether F-250, F-350 SRW or F-350 DRW. Here are the springcodes for the front leaf springs on '99 thru '04 PSD 4x4 pickups:
T = 4,400 pounds @ground
U = 4,800
V = 5,200
W = 5,600 (rare on a pickup)
X = 6,000 (only with snow-plow pkg on a pickup)
Rear springcodes:
A = F-250 & Excursion (6,084 pounds @ground)
B = F-350 SRW (6,830 pounds @ground)
C = F-350 DRW (8,250 pounds @ground)
If you already have code B rear springs, then you already have the same rear springs that are on F-350 SRWs.
If you have Code U or V front springs, then you might like the code X front springs. In addition to giving you a little more weight capacity on the front end, they will give you a one to two inch lift of the front end.
If you wanted to really beef up the springs on your F-250, then put the code X front springs and the code C rear springs on it (they should bolt on). But be warmed it will then ride "like a truck". <?xml:namespace prefix = v ns = "urn:schemas-microsoft-com:vml" /><v:shapetype id=_x0000_t75 stroked="f" filled="f" path="m@4@5l@4@11@9@11@9@5xe" oreferrelative="t" o:spt="75" coordsize="21600,21600"><v:stroke joinstyle="miter"></v:stroke><v:formulas><v:f eqn="if lineDrawn pixelLineWidth 0"></v:f><v:f eqn="sum @0 1 0"></v:f><v:f eqn="sum 0 0 @1"></v:f><v:f eqn="prod @2 1 2"></v:f><v:f eqn="prod @3 21600 pixelWidth"></v:f><v:f eqn="prod @3 21600 pixelHeight"></v:f><v:f eqn="sum @0 0 1"></v:f><v:f eqn="prod @6 1 2"></v:f><v:f eqn="prod @7 21600 pixelWidth"></v:f><v:f eqn="sum @8 21600 0"></v:f><v:f eqn="prod @7 21600 pixelHeight"></v:f><v:f eqn="sum @10 21600 0"></v:f></v:formulas><vath o:connecttype="rect" gradientshapeok="t" o:extrusionok="f"></vath><?xml:namespace prefix = o ns = "urn:schemas-microsoft-comfficeffice" /><o:lock aspectratio="t" v:ext="edit"></o:lock></v:shapetype><v:shape id=_x0000_i1025 style="WIDTH: 212.25pt; HEIGHT: 68.25pt" type="#_x0000_t75"><v:imagedata o:title="" src="file:///C:\DOCUME~1\BRANDO~1\LOCALS~1\Temp\msohtml1\01\cli p_image001.wmz"></v:imagedata></v:shape>
I actually like the ride better, little more firm but not like a hay wagon. I think I gained a little more stability from the x-codes too. Your drw would already be more stable, so I don't know if you will notice that. I think with a long wheel base x-codes ride better than v-codes. Now if you had a standard cab it would ride horrible, I know I have ridden in one. I think you will like them.
anyone else got a set of x codes laying around they dont want? ive been looking for a set for like a year and have never been able to find some. every time i hit up the pic-a-part or a different junkyard thats the first thing i look for..........
