Above is the link to the product Mikey09120 is talking about. I'm curious what they use for axleshafts besides the stock plastic 3.3 units. I wish there was a longer alternative to the Traxxas cvd's. They pop out on me when using the extened arms and I have the required longer drive cups.

Hmm, even longer drive cups?

Stockers should be fine, but you could always have a poke on ebay for some telescoping steel driveshafts- kind of a cross between the stockers and cvds...

thanx for posting the link. i forgot
that problem could be solved by screwing your pivot balls in more or maybe aftermarket CVD's
you should call traxxas and make a complaint. if you do get these axle carriers then you will definatley need longer drive cups.
also how are those CVD's working
any performance improvements?

A temporary solution for the loose drive axles could be dropping an O ring at each end inside the drive cups. This would keep the drive shaft from wandering too far in either direction and possibly keep them from popping out alltogether.

Not sure how an O ring is going to keep the "dogbone" end in the cup? I'm just saying what happens to my Traxxas CVD's will not stay in the cups if you run the traxxas extended wheel base arms and the stock knuckle in the 19mm position. I did try screwing the piviot balls all the way in and same problem. If I take a nice big jump at about 40 mph those cvd's will pop out of the cups. I have since moved to the 10mm position and have had no problems. If anyone has a link to longer axles shaft, even if its not for the e-revo but looks like they might work, let me know. I'll try them with the qoncepts extended wheelbas axle carriers.

If I understand your issue correctly, it sounds like either the drive cups are too shallow(which they aren't because you have the extended drive cups) or the traxxas CVDs are too short...or, you have so much change in the length from drive cup to axel carrier through your range of travel, that could be the issue.

The point of the O rings(place one in each drive cup before putting in the CVD) would be to take up any space between the end of the CVD and the closed end of the drive cup.
If it's coming out of the top drive cup, an O ring in the axel carrier's drive cup would possibly keep it from happening...see what I'm saying?
Here's an ASCII pic:

WHEEL-<o|=----=|o>-DIFF

-< is a drive cup
| is the CVD pin that slides into the drive cup slots.
o is the O ring
= is the hollow portion of the drive cup
- is the CVD shaft

Anyways, take it or leave it. Just tryina help.

im having same issue with my teckno swayback arms and traxxas cvds + i have the extended drive cups to. the keep popping out

J3110, thats the same solution, they used a few years ago with the 1:10th onroad car's dogbones.
the O-rings where included.. are the not included with the CVDs?
