The O'Rings behind the planetary gears put more load on the diff causing it to behave like it has much much thicker oil in it. I would only use them in extreme circumstances as you will end up with a huge amount of drive, like crazy amounts. Very very few people use that style of setup as it can become incredibly difficult to drive but it will be fast if you can drive that style of setup. If you have the skills of Lutz or Savoya, go for it, for the rest of us meer mortals, not a hugely useful setup.

its just more consistent to put heavier diff oil in rather than try to use the o rings to get the same effect

The dog bone, the ones that turn the outdrives. The ones you need a press to remove, the ones that are preinstalled.

Default where does the oil go ?

i now have about 2 gallons on my 1st nitro buggy. i thought i was overdue for checking diffs and changing oil. i noticed upon teardown there is almost no oil left. there was a little less than a 1/4 inch in the frt and rear diffs and a little more thatn that in the center. i have always kept my ride pretty clean and always check for any type of fluid leaks.never saw any indication whatsoever that there was a leak...anywhere.when i filled these initially i filled the fluid up to the cross shafts and let sit for an hour or so and rechecked.
my other question is regarding my shocks. during a run at a local indoor track i found my r/frt shock was binding up,enough to keep the suspension from extending. after checking the shock shafts and feeling confident they were straight,i chalked it up to being dirt in the shock. drained cleaned(w/o spray cleaner) and replaced the oil it was fine for a few minutes and bound up again. this binding is very very intermittent by the way. when i got home i tore this shock down again and inspected with a magnifying glass and found the shock piston had a slight distortion to it with what appears to be fine threads of plastic on the side of the piston. at this point i replaced the pistons with the black 6 holes. cool everything working great now ! went to the track on fri nite and it happened again. took the shock out and i could get it to bind ..sometimes 3 out of 4 strokes,sometimes once every 50 strokes. but when it binds it takes an act of congress to get it to release again. checked the shafts again and found no problem.i finally loosed the nut on the piston about 1 turn and loosened the collar on the seal pack slightly and hasn't bound up again ( yet...)
any input is appreciated

Sounds to me like your pistons were overtightened...Run your seal retaining cups finger tight.. Sometimes I leave mine loose and apply a touch of blue loctite if they feel tight.

On the diffs, you can't run that car 2 gallons and expect the diffs to be full...Service them once every other race if you want optimum performance.
