which diff is stronger...
 

The new 3905 e-maxx diff or this http://www.rc-monster.com/proddetail...zerdiff&cat=47 I am needing one for my 1/5 scale e-maxx/baja. I will be running 7s2p a123 with a kb-10l. Thanks.

I would use the 3905 diff with the flm al cup and some sort of al case.

LST diffs. Go here:http://www.rc-monster.com/forum/showthread.php?t=9153 Hope it helps!:yes:

if you use 3905 diffs with the flm 3mm diff cup, theres only one company that makes a AL diff casing, which is golden horizon. heres the cheapest place i found them

I did this myself, actually was going to sell the required parts to do the swap, but did not find a suitable front case support to modify to fit the lst case. And I did not feel like making them myself...

If you want to some (bullet proof diffs) get these.. I have them and they are great!!, i been running run them on my GR3 E-Revo on 6-8s for the past 8 months and have had no problems at all with them..

Just a thought.. :whistle:

P.S.
Yes I know you mentioned the 3905 and these are Revo diffs, but hey that’s why there is fabrication..:wink:

I don't think you can use the flm cup with the 3905 diffs. the 3905 diffs are basically revo diffs in a case that fits in the maxx bulks. right?

Near the bottom of this page they list a specific 3905 cup with gear. And they have just the cup to work with the stock 2.8mm bolts.

id get the 3mm screws for the extra $15. let me know if you find another company that makes AL cases other than the golden horizons one that i linked. i think i remember reading someone had to made a few mods to make it fit correctly.
