Cranks breaking is a complex discussion, and harmonics seem to play into it, but no one has found a real solution yet. Luckily, it is also fairly rare, especially on trucks with stock internals.

Many people run the ATI/SoCal Diesel damper. I run the ATI damper on my balanced rotating assembly, and my brother's truck ran it on a stock motor after we spun the stock balancer off under hard acceleration + traction loss. It seems to smooth things out quite a bit on a stock motor.

This is just my opinion, but i don't think I'd bother changing the damper without addressing the other issues.
