30 spline dana 60 strength

Is it possible for 30 spline dana 60 axles to have any kind of decent lifespan with big tires (40") or is it unwise to even attempt it. It would be in an 88 dodge 1/2 ton less than 350 hp.

If you are street only, go for it. If you are going to wheel it with a locker, I would look into putting some 35 spline shafts in it.

I ran 42's on a fullsize bronco with a 460 and a welded front. Never broke one. Depends on how you wheel it.

If you like the rocks at all,dump the 30s as soon as you can afford.1 broken stub can cost more than the upgrade if you take out the spindle,wheelbearings,and lockout with the stub.Not to mention what a PITA it is to torch the spindle nuts out in a field.Just my opinion, was running 39 IROKs with a tired old 350 and not spinning the tires with new spicer stubs.
