Re: Pro gear users please step in
Thanks to all who responded. Jim- I'm where you are. I certainly prefer to have a bit of insurance with the pro gear.

Re: Pro gear users please step in
Just curious, but what is the metrology and surface treatment difference between a "street" and a "pro" gear. I know the gear guys for over the road transmissions really like a 8620 gear with a carburized surface. Gives the "tootsie roll" effect. Hard on the outside with soft gooey center

The pro gears are 9310 the heat treat should be pretty close to the same with 8620, carburized with probally .060 case depth.The 9310 Pro Gears will be tempered at a higher temperature to take away the brittleness .The higher the temper the softer the gear, Pro Gear i would think would be 55rc to 57rc where a street gear will be 61-63Rc .The 9310 will have a tougher core harness then the 8620 which should help with rolling over the teeth..Hope this helps
