The part number for the 4.2 rear tower is 9573 the 4.1 is 9572 so there is a difference.

part number pulls up stock from a bit back, so it appears to be a running change like others have described.

9573 is the carbon tower and the 9572 is the plastic tower.

Nope, there is not a different part number for the B4.1 or B4.2 tower.

ASC9572 is the Standard
ASC9573 is the Carbon

but they both show B4, B4.1, B4.2

I just found this

I know someone who is about to spend some $ coughassociatevalleycough

If those rear 0* hubs with the vertical balls are the same height as the c-hub tower I will be very interested in them. I'm guessing they are since they make mention of the u-brace being "shaved". Does anyone know where to find more info on yaiba racing in English?

They dont 'look" like C hub elevation, but it is a picture. Honest, I like the 2 piece idea of the AE hubs, I just dislike the quality. I have broken about 15 studs off in the plastic uppers. Back when Losi had a hub like that, I used to break studs off in them also and getting the threads out also sucked. The carbon uppers are nice, because if I break it off, it is easy to remove the stud. But, I have never broken one off in the carbon. I assume it is because of the nut on the back or the the flex in the carbon.

Real cool stuff that is different from the everyday AE blue.
They don't have these new releases but have a few items.

It states on their website that when you use the 2 supplies spaces under the ballstud, it matches C hub height.

"
- You can adjust the upper arm pivot ball position using spacers.
- It has same position with Team Associated C-Type REAR HUB CARRIER when using included spacers 2pcs for each side.
-It is 46% lighter than Team Associated ALUMINUM REAR HUB CARRIER.
"YAIBA-RED" anodized.

When it says each side. I assume it means the front to rear hub position. But it may mean 2 spacers to raise the ball stud for each side. The English could be better I guess. They do look nice in red. I would still be concerned about breaking studs off in the alum hub.

Im liking those hubs, just wish it was blue to match the rest of the car (coming from someone running red crc batteries lol)

Someone makes those too.

Those are a-hub height but 0*. The racers edge, iirc, are c-hub height but .5*. These, afaik, are the 1st to be c-hub height & 0*.

I got these numbers from associated manuals for the b4.1 and b4.2. Must mean the 4.1 comes with plastic and the 4.2 comes with graphite.

I am sure there will be a lot of guys ordering the new ones to replace the old dremel ones.

Could be. I know the pic of the B4.2 on RC10.com of the Front Shock Tower really looks like my Carbon bits.But according to the manual the part # is for the regular plastic tower, not the Carbon Front Tower. Ironically I don't even see a part number for the Rear Shock tower in the actual instructions part of the manual, just the little exploded parts listing at the end. I guess we won't know for sure until we get our hands on it. Ordering one or the other will only determine which plastic you get though net if you get a "new" tower or not. If you go to the parts page for the b4.2 it even shows both towers but neither show the added material of the new towers.
