I'm sure this is a basic question.. But ARB told me they make a air locker for any spline count offered in my Dana 60. But I was told by another person," I need to get new 35 spline axles for my free floater and I probably have 30 spline now".
I know the 35 would be better. stronger. But would a 30 spline work if I didn't run big 33" wheels? what are the limitations to the 30 spline?
This is for my cummins powered 95 E350 tow vehicle.
I'm also trying to decide which locker or limited slip diff I need. I can afford the ARB, but I'm worried about a family member or friend forgetting its turned on and locked.
Thanks
