bolt in sprag?

Dumb question I know but want to make sure. Is this the bolt in sprag people are telling me to get?

That is an absolute waste of money unless you have already spun the outer race in your case.

Why are you switching to a bolt in ?

the bolt in to buy is either the one made by A+A or Coan , they have extra rollers and are virtually impossible to fail. , they aren't cheap though , almost $200.
