I do not think those will work. The only center CVDs I've seen so far specifically for the E-revo are from Integy. Kershaw Designs makes center dogbones, but no CVDs yet.
I bought some Revo center CVDs and they were the wrong ones, that's how I learned the hard way. Now I decided to keep the stock plastic center shafts. I am keeping them as a weak link on purpose, so that they will break before my expensive F/R CVDs or expensive V3 hybrid diffs. If you replace the stock center shafts with CVDs something else will become the weak link, and it might be something much more troublesome and expensive to replace. Just something to consider.
Also, if you are having trouble breaking center driveshafts try loosening the slipper a bit so it slips more on hard impacts.
I wouldn't go for the CVDs. Personally I would like something to give on a hard impact or landing.. The stock driveshafts and cheap and easy to replace.. If you get CVD all the will end up going to your differential. Plus if you adjust your slipper just a bit you shouldn't be going through driveshafts all that much.
