It is the CKP reluctor wheel. If you are using an LT1 crank hub, you need it to keep the spacing correct for accessory drive.

...or delete it and use a slightly longer 93-95 hub. I suppose it depends on what timing cover you are running.

You're going to need the longer 93-95 crank hub in order to keep the accessories in line.

Some people have reported using the shorter hub without the CKP wheel with no problems though. The pulley will be about .1" out of line.

You are also going to need to shave the crank key down or swap it with a non-crank sensor key. If you don't, the longer hub will bump up against it and not seat all the way to the crank gear.
