Since you guys actually know what youre talking about, not to mention you dont seem to mind answering my noobish questions, here it is.

What is it going to take to put SD axles in my 92 F250? Axles are from a 02 F250, D50 / 10.5.

From what i remember, the front spring pads should be fine, but the rears will need to be moved in. Any info regarding pitman / drag link would be helpfull, as well as any info on which, if either, panhard can be used. No lift or RSK , using OBS F350 springs up front, keeping the 3/4 springs in the back and will probably add bags at some point, sure i will have to find a taller block.

 

from what i remember the difference in spring width is something like 3/4 inch.

 

If i remember right the fronts are also 2.5" longer, idk about the other stuff

 

That is on the rear correct?

Longer? Are you talking about the SD springs vs. OBS springs?

 

front and rear. i seem to remember one of the guys that put a SD 60 and 10.5 in his obs truck saying the spring perches were 3/4 inch narrower than the obs truck, and he just twisted the springs a bit to bolt them up. said it worked, but i did not pay much attention to the build after that.
and that was around 2 years ago or so.

 

Yeah, OBS vs new SD springs

 

Well damn... that sucks, was thinking the front at least was more or less a direct drop in. I suppose the left side perch is an integral part of the housing?

 

Can anyone attest to RSK's making the truck ride nicer? Would probably be the only reason i would consider it, more than that i was thinking of having a custom spring pack made. Not that i want to... but i need to keep it "not-lifted" as much as possible to be able to hook onto trailer without having to always adjust the goosneck.
