Will a factory e locker from a rubicon fit in a rear dana 44 sahara?

 

The Rubi's rear D44 is just slightly different than the non-rubi D44. To be honest, you are MUCH better off with that non-rubi axle if you want to add a locker. the Rubi e-locker is about the worst option there is. I can see how that might not be what you want to hear if this is a case were you could get a rubi locker super cheap, but it's the truth. I'd personally go with a 35-spline eaton e-locker if you are at the point of adding selectable traction in the back.
