You can SOA any vehicle...These going into a YJ I presume? It's alot of work to make it right. Many people do it half a__ed and break stuff since they failed to understand "axle wrap". You MUST compensate for this.
I've seen this done alot:
a) rear shackle flip
b) new spring perches on top of axle tube
c) longer U-bolts
d) steering conversion highly possible
e) longer brake lines and e-brake relocation
f) drive shaft work
- rear CV shaft I believe
- front lengthened...?
g) could be more I've missed
You need to know what you are doing, this is NOT for a novice at ALL! Welding also required.
Here's a link for a complete kit

Outside of the frame?
Where on earth did you come up what that information?
