Title: 1310, 1350, or flange?
Post by: Black Betty on November 20, 2011, 10:27:54 AM

I have a '94 yj that is bone stock.  Long term plans is to have a soa lift with probably a dana 44 front and a ford 9" rear.  For now though, I will be putting on a 2.5" ome lift with 5/8" lift boomerangs on all four corners.  I know that I can probably get away with a t case drop for driveline angles, but due to the leaking rear output seal on the tcase, and the long term goals, I will be installing a sye.

I have decided on the jb conversions super short, but can not really determine which output yoke to order it with.

The options are a 1310 cv style, 1350 none cv, and a rear output flange.

I'm going to guess that the rear output flange is not required, and will end up shortening the overall ds length?

So this leaves the 1310 and 1350.  I would think i need the 1310 set up for a cv.  Am I correct on this?  Can someone explain what these three options would be for?  And point me in the right direction?

My jeep is a 4.0 with ax-15.

And I did a search already, but didn't come up with a specific answer.

Yup 1310 will be the right size for your stock diffs and the Dana 44/9". 1350 is for big diffs (one tons).

Side note, you can run a flange as well. That's what rubicons come with so you may be able to use a rubi drive shaft. I'd go yoke though.

If you are unsure of what direction your build is going to go you should check out the custom flange that Tom Woods DS is making. It will allow multiple types and sizes of ujoints and shaft's to be used all without having to change the flange. It's the Super Duty Tail shaft conversion, the flange allows for: 1210,1310,1330 & 1350 series drive shafts to be used without changing the flange.

cool, the 1310 is the cheaper option, and allows for a steeper ds angle.  Anybody else run this super short sye?

I have the JB SS SYE kit and it has been great.  You will need to get the conversion pigtail from Jeep to be able to use you stock speedometer since the SS kit uses a tone ring.  I have still have the part number somewhere
