Academy offers delrin diff rings and pinions, as well as delrin slipper spurs...do you know if they are worth having? Can you run both aluminum and steel pinions on delrin spurs?

Are the delrin spurs different than the stock ones?

I don't see why you would have an issue using the metal pinions with the delrin spurs.

Well, the stock diff rings & pinions and the spur are molded, while the delrin gears are machined and the quality is much better.

you got some stock numbers?

I will find them, hang on...
