Looking into lockers for the rear
Hey guys and gals I'm looking into getting an Aussie locker for the rear diff, I know it is a Hp Dana 44 open diff with 3.21 gear ratio, can any one tell me how to find out if my axels are 35 spline or 33 spline?????

Front
Non Rubi - 27 spline inner / 32 spline outer
Rubi - 30 spline inner / 32 spline outer
Rear:
Non-Rubi - 30 spline
Rubi - 32 spline
A lunchbox is inexpensive and works great up front, but may not be your best choice for the rear axle. If you can swing it, consider moving up to a detroit instead.
Just noticed where you are. I'll change my opinion to 'consider a truetrac or selectable' instead...

I don't think Aussie makes a rear JK locker. Save your money and when you swap gears do the locker at same time. Aussie has a front JK locker but if you by that and then switch gears it won't work with a standard 3.73+ front Carrier. I went with Aussie in front and a Detroit Locker in the rear.
