Our HARDKORE Tool Steel Cams are designed with a pressed on, and pinned Distributor gear.
This allows for a much tighter tolerance in concentricity between the gear and the cam centerline.
On conventional "1-piece" cams, the gear is machined on the cam before it's heat treated, where it distorts and bends, greatly effecting the gear's concentricity.
Our gears can also be replaced if they're ever damaged.
