The question is how hard(Rockwell C) do you want to make it? You can try hardening it to 60 Rockwell C to make it extremely hard but then it'll be very brittle and prone to shock forces or you can make it not as hard but it'll have a greater chance of twisting. I recently snapped an output shaft that was induction hardened. I thought about cryo treating a stock output but I decided to leave the output shaft alone so I can save up for a Sonnax shaft if it breaks again.

I was reading about this very briefly here a few months back, a company out of Utah? They where claiming input/output shaft strength was increased considerably.

why would cryo treating make a shaft brittle it does not change hardness.

There's a picture running around here that I have saved on my computer at home of an output shaft that had a hardness of 60-63 after being cryotreated compared to a Sonnax shaft which is hardened to around 52. The only problem was the original hardness wasn't posted before the cryotreatment.

Cattlepuncher, usually an output shaft won't damage anything. The output shaft on mine didn't create any damage but when the input shaft shattered on mine it really made a mess.
