That's very tasty info but I expect a deep discount if I have to put them together:lol:

One more if you will, are the HB diffs compatible with the old 3906 cases?

Thanks again!

Oops 16mm od, guess they wont... disregard above!

Hot Bodies lightning series, Ofna Hyper 7, 8, 8.5, Jammin, Kyosho mp7.5 diffs are all known to work in the Hybrid bulks. Any diff that is similar sized will work(some other vehicles use these same diffs, for example).
Mugen, AE, Losi, XRay diffs will not work directly with the Hybrid bulks, as they are smaller in size.

Thanks for your help and info on all of this everyone, I appreciate it! :great:

I think I will just go with Hot Bodies Lightning diffs, at least they have a bigger ring gear tooth count/smaller pinion gear tooth count than my Maxx diff's so I will be able to use bigger pinions on the motor.

The Hot bodies are great diffs. You wont be disappointed.

Sorry to revive a sort of old thread, but will Hyper ST diffs (non pro version, the 6 bevel/spider gear ones) fit in FLM hybrid bulkheads? I can't seem to find the bearing size anywhere. :neutral:

8x16

Just purchased 2. :yipi:

excellent choice. shim out any play when installing in the bulkheads and you should never have to open them. I run 7k oil in front and 5k out back.

Thanks!

I knew there was something I forgot to order at RCM.:whip: I bought the output shaft things to use Revo shafts and a new 13t mod1 pinion, but forgot diff oil... I might just put 10k in both of them since I have some left.

Gotta love Ebay though. I only paid $16 each for a complete diff with pinion gear and some other goodies, total is $40 & some change shipped.
