The x code is the heaviest leaf there is for a 99-04. It is the snowplow prep for the F250/F350 and is the standard spring in the F450/F550.
They are NOT know for their stellar ride, but know for their ride height

 

I have them on the front of my truck, details in sig....I orgigonally had V-codes on there when I went RSK and ended up swapping them out with X-codes....didn't really notice too much of a difference in ride quality, but it did raise the truck an inch over the V-code springs.

For comparison, now that I have the stock bumper back on, my truck when measured from the center of the lockout to the bottom edge of the fender sits only 3/4 of an inch higher than a friends bone stock F350 SRW 4x4 PSD with stock springs and no RSK....fyi mine is a Low Lift RSK.

Here are pics of the two trucks side by side.... regular cab on right is bone stock '95 F350 SRW mine is on left with Crew Cab x-code front springs and Hard Knox Low Lift RSK.....

 

I've done they...X codes are rated 6k lbs vs 5200 for V codes and will get you aprox 2" more lift..they have their usage..heavy winch bumpers or someone trying to fit 37" with a rs kit and keeping a better ride quality.

 

the pound ratings on the spings, is that 6000lbs apiece or as a pair? Is that pounds per inch of movement?

 

Thanks for the info guys!

So the general consensus is that while not ideal, they will ride better than the OBS leafs. And theyll give ya more lift. Ive been reading the Modified Height thread and it sounds like the new 3" Sky kit + Vs puts the truck
s suspension at 26". IIRC im at 26.5" now (ill have to double check it tomorrow). So if the Xs give you that much more lift than the Vs, its possible i could go from an old Sky 3" to Xs & a 2.25" PMF kit, and end up pretty much in the same place as before. Thoughts/opinions?

 

Your math sounds right. I like the PMF kit better because you dont drill any holes and you keep your stock spring hanger under the front cab mount

 

get the new 4" Sky kit will ride better and use v codes, We work closely with Sky. We have everything needed.

Or just relocate your old kit and use SD springs.

Either way we can help..been doing these since '99

 

Good, glad to hear someone agrees with me. I got the pair of springs for $40, so i couldnt pass them up. Even if i dont end up using them, its not like im out much.

I like the PMF kit because off all the extra options it offers, plus its nice that i dont have to remove the rear hangar. Ive been thinking about cutting up my old Sky RSK to add a front receiver, this way i wouldnt have to.

 

Pair....total capacity.
