This was a running change. No change in the part number. There are 3 different versions of the losi diff cups. You've got the HD's, the standard 2.0 spec cups and the old 1.0 version standard cups. The 2.0 spec cups come on all 2.0 rollers. They're stronger than the old version, but the same weight.;)

has anyone noticed the change to the steering ball ends aswell
i got a new car a couple of weeks ago and the new ball ends have an extra ring around them to beef them up a little

Yep they've been around for a couple months now. They seem stronger.:nod:

but i had the same problem as you had with the diff cups
i ordered some new ones and got the old version

its a pain in the arse. its like spinning the lucky wheel when you make an order
i have 3 packets of the old diff cups and 2 packets of the old spec ball ends.
the old version diff cups dont hold up in the truggy so they will now go to waste

Yep that's the bad part about running changes. You really never know what you're going to get... Even years after they've been updated I guess. But hey, at least they're improving things.:nod:

rear diff shims
 

question guys, I started to rebuild my rear diff, I installed the alum spacers with no shim on the rt side(gearside) and 3 shims on the left..with the cases closed tight by hand but not screwed, it feels VERY notchy but not binding,if remove one shim it's notchy but not as bad(this was dry-no grease) which "feel should I go for? I'm trying to get a feel for it, still waiting for the new case to arrive. will the notchyness eventually go away after the gears get seated? thanks for any info.

I would start with 2 shims on the left and 2 on the right. Then once it breaks in 1-2 gallons go with 3 on the left and 1 on the right

You've got it bud, I personally would go for the less notchy setup. But I have tried real notchy and it eventually broke in. I've never had no shims on the gear side though. I usually have one fat and one skinny on gear side and five or six assorted on the other side.

make sure you test it with the diff case screws done up tight
holding it together wont give you the true indication yoyu are looking for

10-4, I'll try the 2-2 set up when the new case comes in and also put the screws in it to try to get a light to medium notchy feel. roughly how many tanks of fuel before the gears wear in?

man im glad that i have, the 1.0 t i never had diff issues like the 2.0 seems to have.

the diffs seem to hold up on my 1.0 buggy/truggy.

i wonder if you guys can just use the 1.0 diff cases ? than maybe you dont have to shim.

sorry double post lol.

LMAO:lol::lol::lol::lol::lol: Why would you be GLAD you have a 1.0?:confused: The 2.0 runs circles around that thing in every way. It really isn't that hard to keep the diffs shimmed right. Just a little bit of maintenance, that's all. That's a really silly reason to be glad you don't have a 2.0.

its just shimming. Im on my original R/P
