Maybe Mopar is right!

For anyone that's interested I spoke to Timken and found out that their hubs are 9mm thick. They are manufactured by Bearing Technologies in Avon, Ohio. BT is the ONLY manufacturer of aftermarket wheel hub assemblies in the US, so I suspect that these are the same hubs as the NAPA/SKF ones, as NAPA does claim that their 9mm hubs are made in the US.

so those of you that check your axle bolt every race...does that mean you remove the cotter pin and the keeper every time or just removed them all together.

I have a set of MP hubs on my bench; i am going to get them cryo-frozen before installing them.

Yep, take the cotter pin & keeper off, check the torque, and put em back at least once every race weekend.

We run cryo'd Timkens on our car.

I leave the pin off all the time and torque after every session.

I ordered a set of Timken hubs and when they arrived they came in an SKF box. So, that would confirm my suspicion that they are the same hubs as those NAPA sells. I put a micrometer on them and verified that they are 9mm thick at the flange.

I had them pressed onto the knuckles and cryo'd both assemblies (hub,bearing,knuckle). Ran them last weekend in an enduro and will run another 4 race weekends or so then replace.

I'm thinking of sending them to a metalurgy lab when I pull them off to get an analysis done to find out how much fatigue has occured. I am interested to know if the cryo makes a huge difference. Anyone have a hookup to a metalurgy lab who might want to donate an analysis for the sake of research?
