8 spyder diff
 

Ok so today i put togeather my 8 spyder diffs, and they are lookin pretty good. Too bad i still need center CVD's and and ESC to get my car togeather. I was wondering what diff lube i should use and what weight. Here is my car specs:

Gmaxx X-Brace aluminum chassis
Integy racer X suspension
SuperMaxx CVD's all around (center on the list)
Big Joe Tires with Velocity 6 rims
one speed converted tranny with supermaxx idler
Hacker C50 running 12-16 cells


Well those are probably all the things that really matter in this decision. Thanks

**Edit** My dad owns an auto shop and i was reading that i could use grease? I can get some specs on what he has tomarrow, i know its some green stuff used for packing bearings in cars (Mercedes). Also im building this car from scratch, what else needs grease or lube? Do i need something on the outside of the diff, in the housing? and what about in the tranny??

You might find this useful;

You should not use grease inside the diffs, because normal grease would be too thick and it would change viscosity once it gets hot. Silicone grease is known for it's constant viscosity temperature wise.

well so somewhere between 1,000wt and 30,000wt
what do most people use?

Id reccomend 10K weight oil.

and for tight tracks, you could use a little lighter. the thicker the oil, the better it will stay in..

7k front 5k rear is commonly used.

I use 7k both front and rear.

what kinda stuff should i use in the tranny??

nothing in the tranny.

"....They are a direct replacement. No modifications need to be made to your transmission. Simply follow the Traxxas exploded diagram replacing your stock plastic gears with these and you will be fine. We do recommend using a good quality grease (not included). Traxxas runs the Transmission dry and this is not reccomonded. This transmission is operating in a speed range that necessitates lubrication." From Unlimited Engineering.



I recommend Associated black grease.http://www2.towerhobbies.com/cgi-bin...?&I=LX2880&P=7

For stock plastic gear's, grease isn't needed. If you upgrade to alum/ steel idler's however, it is needed. Like in this case.

Keep in mind the stock tranny isn't sealed. Don't pack it with lube, a small amount on the gear's is enough.
