The shaft assemblies I buy are pre balanced. You install the compressor wheel using the balance marks provided on the shaft and wheel.
(Just my opinion) I'd say the chances of it snapping had I left it alone where MUCH higher vs replacing with cheap unbalanced shaft. (judging by the massive crack in the shaft, and another I noticed later on but didn't take a pic of) but the crack in the rear of the shaft is just under halfway thru the shaft. Disaster waiting to happen... first time I have seen that...
The old shaft will spend the rest of its life on a display shelf as an example.
But I digress..
Spools great. Runs great. Turbo runs cold now
