Spline Count Dana 44 Rear and 30 Front?
Im going to be regearing my 2009 JK Unlimited (Auto transmission with stock 3.73's) with 5.13's to run 35's. Does anyone know what the spline count is for the pinion on the Dana 44 HD Rear Axle? As well as the spline count for the front Dana 30 Solid Axle? Answers will be greatly appreciated!

I've tried without success to find a 30 spline setup for the D30. ARB makes a locker/carrier, but there don't seem to be any 30 count axles for a JK housing.

Correct about the D30 being 27 spline. Also correct about the D44 being 30 spline. ARB does make a D44 35 spline carrier but the only company that makes 35 spline axle shafts is RCV as far as I know. The RCV is a very strong axle shaft however it is also a very expensive axle shaft. If you would like any quotes on anything let us know.

Outers are 32sp on both the JK d30 and d44 front axles.
Non-rubi : D30 Front - 27sp inner, 32sp outer. D44 Rear - 30sp
