Default How strong?

How strong are the 30 spline dana 60 axle shaft? I run 38s and a little hp. I pulled mine apart and the shafts look small.

so you're saying a 30 spline 44 shaft is as strong as a 30 spline 60 shaft?

30 spline dana 44 and 30 spline dana 60 shafts are both 30 spline 1.31" identical shafts.

30 spline does not equal 30 spline always (if the diameters are different).

But in this case, yeah, 30 spline dana 60s use 'dana 44' shafts..

front or rear?

front 60 has 30 spline as its weakest point, front 44 has a 19 spline as its weakest link.

rear 60 full floating has the same spline as a semi floating dana 44 like previously stated.

The shaft is the same size with comparable strength.

The design of the full float puts less strain on the shaft. So you get to use all of it's available strength to turn the tires, not hold the vehicle up AND turn the tires.

ding ding ding.. we have a winner. run the 30 spline til you break it. which if you do most of your wheeling in michigan you probably wont. if it does you can either start carrying spares or spend the time and money to do the work of changing it over to 35 spline.

Im going to run them for now. IM taking a 70 out and putting in a 60. I know it is dumb but i have to give the 70 back to my buddy. I hope to buy it later on but for now the 60 will have to do.

I have not busted one yet but I only run mud, I think they are good until you run crazy low gears. Then they shear off pretty easy. But with 38s it should be fine.
