rc-zombies, yes, that is 48 pitch. I run 64 pitch myself. A 94 tooth spur is just a tiny bit smaller than the 70 and a 95 is just a tiny bit bigger than the 70. I have a 95 tooth Xenon Perfect spur on my car. Most of the bearing are metal shielded but I think the large diff outdrive bearings were rubber sealed. I'll have to double check when I go through the car later this week.
