Milodon hardened shaft with bronze distributor gear

T56MaxTorq said

It’s for any roller cam, hyd or solid. The roller cam is usually made from a billet piece of steel, wearing out a normal iron gear. Though I have seen some roller cams that had a iron gear pressed on a billet cam. I ran a bronze gear for over 10k Miles with minimal wear. It will only retard the ignition timing slightly over time, nothing You can’t handle.

Okay.
Bronze gears are for billet cams, no matter what style grind hyd/solid.

The ticket or gear to use with billet core cams... is the crain coated steel gear. It can only be used on the cam its broke in with. You cannot reuse it on another billet cam. They are around 90 bucks. Ive been using one for over 5 yrs.

If you simply ask the grinder to use a cast iron core, not as durable, it will allow you to use a regular gear.
The gear presses onto your existing mp hardened shaft.
So ... you need buy the mopar performance hardened intermediate package...then buy the the crain coated gear and remove and replace the mp gear with the new crain piece.
