    I bought them to sell them and keep 2 of them. It was around $600 I think.

    How much are you going to sell them for? I'm not interested but I was wondering if you were going to make your money back.

    These diffs are made for a brushless summit. It is better to get these aluminum diffs then to keep replacing the plastic diffs from the power of brushless. I am not making my money back because I am keeping 2 diffs for my self.

    When will these be sold at the hobby shops. I finally got my diff rebuilding down so they stay together and those aluminum cups would really help. Try the Traxxas 500,000w or 500K diff oil. That stuff is so thick you hardly have to use your lockers at all. Most of my damaged diffs were from forgetting to unlock when I first started to use the Summit.

    I put 700k in a Revo diff & it helped but it still diff's like crazy.

    OP where did you get the cup's??
    Would you go flip my truck back over??

    Where did you get 700k diff oil I did a google search and could not find it. If it was 70,000/ 70k it would diff a lot but I can hardly hold one tire with the 500k.

    $600 for aluminum diffs that's just insane. You gotta be as rich as Bill Gates to get them. I'd rather spend the money to get another Summit. Just my humble opinion of course.

    That's not insane - it's investment.

    OFNA 10230.. 700,000 diff fluid Stormer.. I wanted heavier, but that is it as far as I know.

    It's $600 for 10 of them. $60 each. Still pricy, but if they do what they are supposed to do, they should be cheap over the long haul.

    The 10 diffs cost alittle more then $600 I would have to check paypal again to see how much I paid. Its around $65ish a diff. Yeah people will save money and time in the long run.

    The Traxxas 500k is better at firming up the diff action. If you put it in the diff and let it set open for 20 min to get all the air bubbles out. That is why grease does not work great it holds too much air and turns to butter while driving. The Ofna 120,000 also works very good when bubble free. Use a bright light to look into the fluid and you can see the bubbles slowly rising to the surface, very slowly. This also helps on shock rebuilding, even 55w will take a couple of min for all the bubbles to float up.

    I am still running the prototype in the rear of mine
    I tried fairly hard without being foolish to get it to fail
    Blew the front (plastic)one out again.The rear is still going strong.i don't think with normal use the diffs will grenade even pretty hard running something else will break first

    Is anyone selling these besides the Germans. I could hardly navigate through the web site. They do have pretty impressive milling capability though. PM me if you know of a link.

    Well I did another step to beef up my driveline while waiting to get a set of those German diff's. I put in a set of center drive shafts # 5650R after reading lots of reviews from E revo and brushless E revo owners. Seems the wheel drive shafts that we can't use anyways bend a lot but the center ones last through much abuse. The brushless E revo owners were having the same problem of twisting driveshafts I had. My last one lost a E clip and the pin worked its way out enough to catch and snap the end of the shaft right off. Seems like they addressed this problem in the 5650R instruction sheet when they say the new clips are prevented from falling out by the aluminum lock ring. Hope this works good for the Summit along with aluminum diff's and RR steel slipper clutch which has worked perfect from day one.

    I've placed an order this evening for a pair, looks like some are still available on the next available batch (this Friday), otherwise I should wait for the next batch made ​​in 2 weeks. For information about ordering process you can contact Georg. I'm very curious to test these diff carier made of aluminium. Because I want to make some testing with different grease and oils, I think that the screw holes of the plastic stock diff housing will not resist so much.

    Scan-sum-IT project topic coming soon with lots of pics about different upgrades recommended on this forum, and others. For now (since some weeks) I plan and gathers all the necessary parts. I can not wait to start!

    Yes !!! I can't wait to try this mod. The bigger tires and Tekin motor put a lot more stress on the drive train. I am always worried when I get a little crazy with the throttle that I will blow another diff or ring gear. I also have a spare set of bearings for everything that I keep packed with marine grade grease. Every time I take something apart I put fresh ones in just for peace of mind. One thing I noticed when looking at Revo diffs was the Summit diff is supported much better by the 3 sets of bearings in the case.

    Drooling already, any updates from others who have installed these. After much research in the Revo aluminum diffs, those all had a fatal flaw of not using the support plates on the HD diff gear set and only letting the cross shaft float in a slot. I am glad to see these have the cut outs like the stock one so if the machining is correct they should last forever and only need oil changes. Now someone needs to make good gasket material to replace that black main one that tears if you look at it wrong.
