ARB D44 lockers
So im finally going to pull the trigger on a Air locker for my rear 44. Im not sure which I need though. I have a 09 X with 3.73 gears, but do I get 30 or 35 spline??

The stock rear 44 uses 32 spline but you can upgrade to the 35 spline axles. I went this route myself. The only downside is that 35 spline donor axles will be harder to come by on the trail if you brake them. But I'm not too worried about breaking them since I don't wheel that extreme. If you end up getting the 35 spline ARB, get a set of HD chromolies and don't look back.

Stock non-rubicon rear axle shafts are 30 spline.
Rubicon rear axle shafts are 32 spline.
Rubi axles have the oddball pumpkins that will not accept 30 spline arb's, so you have to move up to 35 spline shafts if you want to run an arb in a rubi housing. For your non-rubi rear 44, you want the 30 spline arb to use with your 30 spline shafts.
