Strong axle. Lots of options and parts. Full width. I'd buy it for that kind of money and then practice tearing down and rebuilding it, if nothing else.

I've been wanting a 9", I know some basics but that's about it...

I think I'll be picking it up regardless. What I was hoping to find out is what spline shafts this thing might have...also how wide is it?

Here's a bookmarked page I have. Lots of various info...as a truck rear, I think you'll likely have 31 spline shafts and a C7 housing. Don't quote me, though.

Sorry, if I'd known that you wanted esoteric specifics, I would have posted that link sooner. Hope it helps.

Should be ~60" wide, 28 or 31 spline and use big bearings.

60"

the full size trucks/vans w/ 9'rs were mostly 60-65"...but i dont know where those breaks happened...i believe it was 78 or 77-ish got 65"...i'm not positive, and the sources i have show either/or it should be 5 on 5.5 i think....

65" is probably better actually...gives you the option run wheels with more backspacing and have the tires sitting about the same as you do now, or push them out even more for wider stance. JK's are 65".

Lol the gears in my head are turning.

I think I'll pick this thing up regardless of the width and see what happens.

It'll be a process, but it'd set me up for 37s for sure.

Now I know it'll be 5.5" bolt pattern, but can't I just redrill the shafts and brake drums?

Get adapters? IIRC you have the 35 rear? A 9 will get you up to 40's with the right 3rd if you ever go that big.

Yup, s35 kit. I'd like to build the 9" as my "last axle I'll ever need" type of build.

My long term plans don't have 42" tires in them.

So let's say it is a 31 spline axle. Will that hold up to rough wheeling locked on 35s? Or should I go with 35 spline shafts?

If I go 35 spline, it'll just take longer to get this under my Jeep as I will have to build it slowly as I save up money to do this.
