This pump has harden gears for sure??HI, This unit comes with the factory hardness over the standard. The originals are somewhat weak, so we don't even carry those. We consider this unit to be the base that should be run with the sky being the limit on what can be done to the oiling system. We do recommend upgrading the gear set to Boundary set if you are modifying over factory. These are much much stronger. Here are some links to those items stocked here in our warehouse so you can learn more. Hope this helps.
