Which RSK height do I have ?
Just got this super clean 96 F350 CC PSD.
It has 35" tires on it now but I want to install 37" BFG's.
I have searched and read about using the X or U code Super Duty Springs.
Which I also have a Warn 8274 winch & Transformer to go on, so front will be even more heavy.
Need to know how many inches the RSK & which springs that the PO installed ?
So I can lift to clear 37's.
Spring's are inverted.
And the part # for springs

The numbers on the springs mean absolutely NOTHING.
Also that RSK appraise to be the old style that use OBS springs , not super duty springs
SO....
I am going to say that is a SKY 3" RSK and Stock OBS F350 springs

Thanks for the clarification on what this new old truck has installed.
So now guess I gotta decide to lift more with OSB springs or get PFW 4.5" RSK and use X code Super Duty springs.
Of course want the best ride at any cost.
I have read something about the front wheel not being centered ?

You will get a better ride with the SuperDuty springs, but SURELY NOT X codes. they are Much to heavy of a spin for a light OBS. they are the standard spring for a snow plow prep, F450 or F550.
I recommend a U or D code

Are you sure 37s won't fit? I only have ~3" of lift. I have a winch bumper on the front though, which does help....
if it rides good now, you could fab or buy a shackle that is adjustable. You don't need much since you're so close already.
