No not a used shaft just an orginal version. Like a original shaft is like 40 bucks the hardened bronze gear shaft is 145 I don't understand why you need that shaft with a new cam what changes that the original style wouldnt work
It's about metals that don't like rubbing against each other.
If you have factory cast iron roller cam and swap in a billet cam, the original gear material is no longer compatible.
Swap a cast one for a cast one and you can use factory style cheaper gear.
