The D30 is 27 spline.

 

Yea, I know. But I am talking about a 30 spline (super 30) upgrade like for the TJ. I know ARB has one but it's like $800.00.

 

I just checked their Site & it looks like all the D30's are 27 Spline.

 

He's talking about a "Super 30 kit." It comes with 30 spline inner shafts and a 30 spline Dana 30 locker.

The lockers from a TJ Super 30 kit will work, but no one has upgraded shafts to fit the JK yet.

 

Oh!,, got it, now I know more than I knew yesterday, I gotta start ready better.

 

I've got an '07 Sahara 4 door, Rescue Green as well, and am getting a full 5.13 rear Dana 44 axle to swap in. This means that I have to re-gear for the front. I'm thinking since I have to do that, I may want to put in a locker. It's a Dana 30 and I was wondering how you liked your Lock-rite in the front.
