Delrin Spur?

[itbvolks]

I guess I should revise my post a touch.

It's not so much eating pinions but there certaily is some wear (spur is clearly harder and shows nearly no wear). This is Mike's mount, his pinions, and the slipperental. I will say there is some run out within my slipper setup which I would assume is attributing some to the pressure variation accross the gear face. At this point, that is what it is and I don't see it getting better.

My other option is to go back to a std center diff and see how things wear. I do like the idea of the delrin spur from a weight reduction standpoint within the driveline. Just wondering if anyone is actually running one and what they are seeing in real use????
