    RCM Diffs are the best available.

    Run 500k in the CD, less unloading to the front axle.

    The diff are not the problem. You need to replace the blue x-ring with a o-ring. I have 30 or 50 in front, 5 or 10 in rear and 500 in the center. over 3 years with no problems(I race my revo)

    Here is the RCM diffs.

    X Rings are problematic if not installed correctly. However, the RCM setup uses a better design. Take a look at the link and then check out Shelby VNT's Revo Build. He pretty well lays out the advantages of it. I've never had one fail.

    Also I run between 7k and 10 in the front and between 3k and 5k in the rear (with the RCM diffs)

    I have stock diffs in another Revo and run 50k front 500k center and 20k rear. (the 20k is a mix of 10k and 30k)

    Besides Traxxas Revo diffs, there are some Robinson Racing upgrades for the stocker gears, and you can also buy aluminum diff cases, both inner and outer, from a variety of aftermarket manufacturers, like Integy, Golden Horizons, and I think Hardcore Racing. These would direct replacements for the stockers.

    The other differentials available are RC Monster 1/8 scale hybrid differentials. I have a set and they are awesome. 1,000 times better then stock. I must have been one of the guys who didn't have much luck with the stockers because mine were feeling notchy after 1 gallon of fuel, and that was with the stock TRX 3.3. I didn't even do any adbusive jumping, but since I've upgraded, I've never looked back. The downside to RC Monster diffs is they are expensive and you may or may not need to massage the inside of your Revo's bulkheads to fit. Also, you are somewhat limited to the center driveshafts you can run, although the stockers work fine and RC Monster has a custom differential output yoke that can accept the stock shafts. There may be other options, in the way of CVDs, but since I do not run them, I can't really offer much support in that respect. The stockers have held up great for me, thus far. Another memeber here, Intrg8r, who also runs the RC Monster diffs may be able to chime in. He was looking for a possible combination that would work with the RC Monster diffs and allow him to run some CVDs. I'm sure he'll find this thread. Just give him a little time.

    I did purchase the RCM yokes and am currently running those in conjunction with the Stock Center Drive shafts in one of my Revos.

    In the new Revo, I am trying MIP center CVDs with UE (Unlimited Engineering) 8mm drive cups on the pinions. I don't know if it will work, but we will see. Hopefully I'll have the parts to start the build by September.

    Typically, people do not have issues with the center driveshafts breaking, so the center CVD may be overkill.

    Thanks. The diffs are pricey, but well worth it. Still, not everyone's cup of tea, and I can understand that. Bang for the buck, there are many other things a guy can spend the money on.

    Yup. They are. I did the math once and you can buy like 23 stockers for the price of the RCM's, but you never have to replace the RCM diffs!

    Shelby, I'll be sure the post how that works out.

    I just purchased a Brushless E Revo with the 2200 Mamba Monster. I Really like the truck, but I started running into problems right away. First I was breaking U joints in the rear axles, so I bought the Traxxas Cvd's. They worked greak until I blew my rear Diff. I really want to buy RCM Diffs, but the site says they're out of stock and it won't let me email them to ask questions about when they're are going to have more availivle. Does anybody know when or where I can get my hands on a set of RCM Diffs?
