Spicer part grades......

[Emmettology 101]

Anyone have experience with Spicer part grades? The Spicer site lists Prefessional Grade parts. But one on-line store is listing "Red Service Grade" parts... i always try to buy Spicer when I can. Anyone know the difference? I've searched on Google and on Spicer and have come up with nada....

I was searching for the same info and came across your post. There seems to be a huge price difference in the red service grade for D60 tie rod ends. Anybody use the service grade stuff with any luck? I think I am going to give it a shot.
